Asset Library License Terms

Effective date: September 28, 2026

The short version

  • The Asset Library is where you find, share and import build-time assets: models, textures, audio, animations, scripts, templates and more. It is not a store for in-game items or game access; those are sold only in Sparks inside Games.
  • Assets imported from outside libraries keep their original licenses. We show you the license; following it is your job.
  • Attribution travels with your Game. The Editor builds an attribution file into published Games and Exported Games. Do not remove it.
  • When you share an asset, other Creators get a standard license: use it in their Games on the Platform and in exports of those Games, but never resell it on its own or pass it off as theirs. You can opt an asset out of export.
  • If you upload audio, it must be fully cleared: no fee owed to any collecting society, label, publisher, union or performer by Summer or by anyone who uses it. Summer holds no blanket music licenses. If your license lapses, take the audio down.
  • Paid sharing, if we enable it, is priced in Sparks, Summer is the seller, and the author accrues Earned Sparks under the Creator Program. Money never moves between Creators. Payouts follow the Creator Program, including its tax forms and any withholding.
  • Player terms, privacy and refund policies live at summer.games.

1. What these Terms cover

1.1 Parties and status. These Asset Library License Terms (these "Terms") are between you and Summer Labs, Inc., a Delaware corporation ("Summer", "we", "us"), 2810 N Church St, STE 89812, Wilmington, DE 19802, United States. They are Additional Terms under the Summer Games Terms of Service. Capitalized terms not defined here have the meanings given in the Summer Dictionary.

1.2 The Asset Library. The "Asset Library" is the catalog and distribution system, available through the Platform, the Editor, the CLI and the MCP Server, for discovering, importing, sharing and acquiring assets for use in building Games (each a "Library Asset"), including 3D models, meshes, textures, materials, environments, sprites, audio, music, sound effects, animations, motion data, fonts, shaders, scripts, plugins, templates and similar build-time items.

1.3 What may not be distributed through the Asset Library. Only assets intended for use in building Games may be published, shared or acquired through the Asset Library. You may not use the Asset Library to publish, sell or distribute Virtual Content, in-Game items, Game Points, Passport Items, access to a Game, or anything else intended for Players rather than for building. Those are licensed only inside Games, priced only in Sparks, and sold only by Summer under Section 8 of the Summer Games Terms of Service and the Fee and Rates Schedule.

1.4 Four categories of Library Assets. (a) "Third-Party Imports": assets imported from third-party libraries and marketplaces listed at [THIRD-PARTY LIBRARY LIST URL] (each a "Third-Party Library"). (b) "Shared Assets": assets a Creator publishes to the Asset Library for use by other Creators. (c) "AI-Generated Assets": assets produced by the AI Tools, governed primarily by the AI Features and Generated Content Terms. (d) "Summer Assets": assets Summer makes available, carrying the license stated on the catalog page or, if none, the Standard Asset License in Section 6.

1.5 Order of precedence. For a Third-Party Import, the Upstream License controls your rights in the asset; these Terms govern your use of the Asset Library and your obligations to Summer and other Users. For all other Library Assets, these Terms control over any conflicting catalog description, and the Summer Games Terms of Service controls only where these Terms are silent.

2. Additional definitions

2.1 "Acquirer" means a Creator who obtains a Library Asset through the Asset Library, whether at no charge or for Sparks. 2.2 "Attribution Manifest" means the machine-generated attribution and license file the Platform and the Editor compile for a Game, listing Library Assets used, their sources, licenses and required credits. 2.3 "Upstream License" means the license under which a Third-Party Library or its contributors make an asset available. 2.4 "Transaction Taxes" means sales, use, value-added, goods and services, excise, gross receipts and similar transaction taxes or fees imposed by any country, state or locality on a Sparks purchase; Summer, as seller of Sparks, collects and remits them where required, and no separate tax attaches to an Acquirer's Sparks spend on a Library Asset. Transaction Taxes are distinct from any US income tax withholding on an uploader's Program Payment, which the Creator Tax Addendum governs.

3. Third-Party Imports

3.1 Convenience only. The Editor and the Platform let you search and import assets directly from Third-Party Libraries. Summer is not a party to any Upstream License, grants you no rights in Third-Party Imports, and does not modify, expand or replace the Upstream License. Importing an asset does not change its license.

3.2 The Upstream License governs. Your rights to use, modify, distribute and commercially exploit a Third-Party Import, on the Platform and in Exported Games, are exactly the rights the Upstream License gives you.

3.3 License surfacing. When you import from a Third-Party Library, Summer displays the license information the source provides (license name, link, stated attribution requirements) and stores it as metadata on the asset and in the Attribution Manifest. This is informational: Summer does not verify Upstream License data, does not warrant its accuracy or completeness, and does not give legal advice about what an Upstream License permits.

3.4 Your responsibility. You are solely responsible for reading the Upstream License; confirming it permits your intended use, including commercial use in a monetized Game, modification, incorporation into a Mod, and redistribution inside an Exported Game; satisfying every condition it imposes; and not using assets whose Upstream License prohibits your use. Summer may block or flag categories of Upstream Licenses (for example non-commercial or no-derivatives licenses) in the import flow.

3.5 No circumvention; no re-sharing. You must not use the Asset Library or the Editor to circumvent a Third-Party Library's own terms, API terms, rate limits or paywalls, and you must not re-share a Third-Party Import as a Shared Asset unless the Upstream License expressly permits redistribution on those terms and you preserve all required notices.

4. Attribution obligations

4.1 The Attribution Manifest. For every Game, the Platform and the Editor automatically compile an Attribution Manifest from the license metadata of the Library Assets used. It is included with the published Game, viewable on the Game's information page, and written into every Exported Game as notice files packaged with the export, alongside the engine notices described in the Third-Party Software Notices and subject to the Exported Game Runtime License.

4.2 Do not remove it. You must not remove, delete, alter, obscure or suppress the Attribution Manifest, or any required entry in it, from a published Game or an Exported Game. This is a contractual commitment to Summer, to uploaders of Shared Assets and for the benefit of upstream licensors, and it applies even where a particular asset's license would not itself require attribution. Removing or falsifying the Attribution Manifest is a material breach.

4.3 Supplementary attribution. Some Upstream Licenses require attribution in a form or place the Attribution Manifest alone may not satisfy. You must provide any such additional attribution. The Attribution Manifest is a floor, not a ceiling.

4.4 Distribution of Exported Games. If you distribute an Exported Game, you must keep the Attribution Manifest intact in every copy and pass the non-removal obligation through to anyone you authorize to distribute it.

4.5 Corrections. You may supplement or correct attribution metadata for assets you uploaded and report incorrect metadata on other assets. You may not delete entries that correspond to assets actually used.

5. AI-Generated Assets

5.1 Assets produced by the AI Tools are governed by the AI Features and Generated Content Terms and the AI Acceptable Use Policy, in addition to these Terms. 5.2 If you share an AI-Generated Asset, you are its uploader for all purposes of these Terms, including the warranties in Section 8 and the indemnity in Section 10, and you must accurately complete any AI-generation disclosure the Asset Library requests. 5.3 AI-Generated Assets may not be protectable by copyright; the Standard Asset License and the restrictions in Section 6.4 apply as contractual obligations regardless. 5.4 Sharing an asset is not a training contribution; training rights arise only under the Training Contribution Programs in the AI Features and Generated Content Terms.

6. Shared Assets and the Standard Asset License

6.1 Sharing is optional. Nothing requires you to share any asset. Assets you keep in your own projects are governed by the Summer Games Terms of Service and are not licensed to other Creators.

6.2 Grant to Summer. When you publish a Shared Asset, you grant Summer a non-exclusive, worldwide, fully paid-up license to host, store, reproduce, display, distribute, fingerprint, scan and technically adapt the Shared Asset as needed to operate, moderate, secure and provide the Asset Library and the Services, and to sublicense it to Acquirers under Section 6.3 and to Players as embedded in Acquirers' Games. This grant covers hosting, operation, moderation, safety and distribution to Acquirers. It does not include training rights, which arise only under the AI Features and Generated Content Terms.

6.3 Grant to Acquirers: the Standard Asset License. When an Acquirer obtains your Shared Asset, Summer sublicenses, and you grant, to that Acquirer a non-exclusive, worldwide, fully paid-up (apart from any Sparks price paid to Summer) license to: (a) use, reproduce, modify and create derivative works of the Shared Asset; (b) incorporate it and its derivatives into the Acquirer's Games and Mods on the Platform, including monetized Games; (c) unless you have opted the asset out of export under Section 6.5, include it, as embedded in such a Game, in Exported Games of that Game distributed through any lawful channel, including Steam; and (d) sublicense the foregoing solely as embedded in a Game, Mod or Exported Game (for example, to Players of an Exported Game), never on a standalone basis.

6.4 Restrictions on Acquirers. An Acquirer must not: (a) resell, relicense or redistribute a Shared Asset (or a trivially modified version) on a standalone basis anywhere; (b) extract assets from another Creator's Game or Mod other than through the Asset Library or another authorized channel; (c) re-upload another Creator's Shared Asset as their own, claim authorship, or register or assert exclusive rights in it; or (d) use a Shared Asset outside the uses in Section 6.3 without a separate license from the uploader.

6.5 Export opt-out. When publishing a Shared Asset you may mark it "Platform only", in which case Section 6.3(c) does not apply to that asset and Acquirers must exclude or replace it before exporting a Game that uses it. The Editor identifies Platform-only assets in the Attribution Manifest and in the export flow. The marking applies prospectively to new acquisitions. The Attribution Manifest records each asset's export status as of the Acquirer's acquisition, and that recorded status governs the Acquirer's right under Section 6.3(c) for that acquisition, consistent with Section 13.1.

6.6 Pricing and payment. Shared Assets are offered at no charge at launch. If Summer enables paid sharing, a Shared Asset may be offered for a price in Sparks shown in the Asset Library. Summer is the sole seller of the Acquirer's license; the Acquirer spends Purchased Sparks with Summer, and Summer credits you Earned Sparks in the proportion stated for Library Assets in the Fee and Rates Schedule (at drafting [LIBRARY SPLIT]). Earned Sparks so credited are a contingent entitlement to a Program Payment under the Creator Program Terms and nothing more. Program Payments arising from Earned Sparks credited under this Section are Program Payments for all purposes and carry the tax treatment, forms and any withholding on the US-Source Share described in the Creator Tax Addendum. No fiat, and no Sparks, ever moves between Creators, and Summer never receives or holds any amount for you. Purchased Sparks never convert to money for anyone.

6.7 Survival of licenses; delisting. If you unpublish or delete a Shared Asset, or your Account closes, the Standard Asset License survives for copies already obtained by Acquirers and embedded in their existing Games, Mods and Exported Games, so downstream Games are not broken. Unpublishing stops new acquisitions; it does not revoke licenses already granted, except as Section 9 provides for removal for infringement or illegality. Summer's license in Section 6.2 continues for so long as any Acquirer's Game uses the asset.

6.8 Passport Items are not Shared Assets. Passport Items are Virtual Content governed by the Summer Games Terms of Service and the AI Features and Generated Content Terms, not by these Terms.

7. Music and audio

7.1 What this Section covers. This Section applies to every sound recording, musical work, sound effect, synthesized voice and other audio you upload to the Asset Library or include in a Game, Mod or Virtual Content ("Audio").

7.2 Summer holds no blanket licenses. Summer Labs does not hold blanket public-performance, mechanical, synchronization, label or publisher licenses covering Audio you upload. You may upload Audio only if (a) you own all rights in it, (b) it is licensed to you on terms that permit every use licensed under these Terms and the Summer Games Terms of Service with no fee ever becoming payable by Summer, any Acquirer or any Player, or (c) it was generated with Summer's AI Tools and its rights are covered by the AI Features and Generated Content Terms.

7.3 No fee owed by anyone. You represent and warrant that no fee, residual or other compensation is or will become payable by Summer, any Acquirer or any Player to any of the following in connection with uploading, publishing, distributing, reproducing, synchronizing, publicly performing or communicating the Audio to the public, on the Platform or in Exported Games: the owner of any sound recording (label or recording artist); the owner of any musical work (publisher or songwriter); any musical-works performing rights organization (including ASCAP, BMI, SESAC, GMR and non-US equivalents); any sound-recording performing rights organization (including SoundExchange); any union or guild; any engineer, producer, session performer, voice talent or other participant entitled to a share of proceeds.

7.4 Composer, publisher and label duties. If you are the sole composer of a musical work, you must notify your performing rights organization in writing of the fully paid-up license you grant under these Terms and comply with its reporting rules. If you are not the sole composer, you must ensure co-writers do the same and hold written proof of their approval. If you have assigned or administered rights to a music publisher, you must obtain the publisher's written consent. If you are signed to a record label, you must comply with your label contract; authorship alone does not confer the right to license a recording. Do not upload a sound recording unless you are authorized to license both the recording and the underlying work.

7.5 Continuing duty; removal on lapse. You must maintain and continue to pay for every license the Audio depends on for as long as the Audio is available through the Asset Library or in a published Game, and you must remove the Audio from the Asset Library and from your Games on or before the expiry or termination of any underlying license. Section 6.7 governs the effect on Games that already incorporate it.

7.6 Clearances and payments. You are solely responsible for all clearances and payments of every kind (distribution, mechanical, public performance, synchronization, union new-use or re-use fees and any other) arising from your Audio.

7.7 Fingerprinting and scanning. Summer may fingerprint, scan and match Audio against content-identification databases at upload and afterwards, may decline to publish or may remove Audio that matches a protected work, and may require evidence of your license. Publication after scanning is not clearance by Summer.

7.8 Summer-provided audio (dormant). If Summer later makes an audio library available, tracks in it are licensed to you non-exclusively, personally, revocably and non-transferably, only to synchronize into Games and other UGC through the Services and only while Summer makes the track available; Summer may revoke a track at any time for any reason without liability, in which case you must remove it promptly (Summer will try to give advance notice but need not); you may not build a streaming service or music library inside a Game, charge Players to hear a specific track, or exceed 250 distinct Summer-provided tracks in one Game at a time; and Summer-provided tracks may not be exported, extracted or downloaded except as embedded in an Exported Game where the track's license so states.

8. Uploader warranties

8.1 Each time you upload or publish a Shared Asset (including an AI-Generated Asset) you represent and warrant that: (a) you own it or have all rights necessary to grant the licenses in Section 6, and the asset as used under those licenses does not and will not infringe or misappropriate any third party's copyright, trademark, patent, trade secret, right of publicity or other right; (b) for Audio, Section 7 is satisfied, and the asset is not enrolled in any content-identification system in a way that would generate claims against Acquirers' Games or Exported Games; (c) for assets derived from Third-Party Imports, the Upstream License permits your sharing on the terms of Section 6 and you preserved all required notices; (d) all license, attribution and AI-generation metadata you supply is accurate and complete; (e) any script, plugin or executable content contains no malware, spyware, undisclosed tracking or code designed to harm, exfiltrate data from or gain unauthorized access to any system or Account; (f) the asset does not require Summer, any Acquirer or any Player to obtain any license, pay any amount or give any attribution beyond the Attribution Manifest; and (g) the asset complies with the Summer Games Community Standards, the Content Maturity Policy and, if AI-generated, the AI Acceptable Use Policy. 8.2 These warranties supplement the warranties in the Summer Games Terms of Service. They are made to Summer and, as to Sections 8.1(a) through (c) and (f), also for the benefit of each Acquirer.

9. Moderation, takedowns and removal

9.1 No pre-approval. The Asset Library is moderated by automated scanning plus post-publication review. There is no human pre-approval gate, and publication is not endorsement or clearance by Summer.

9.2 Intellectual property complaints. Notices, counter-notices and repeat-infringer handling for Library Assets follow the DMCA and Intellectual Property Policy.

9.3 Removal. Summer may remove, restrict, quarantine or delist any Library Asset that it determines in good faith violates these Terms, the Summer Games Community Standards, the law or a third party's rights, or that is the subject of a valid takedown notice, and will notify the uploader with the basis except where immediate action is required.

9.4 Effect on dependent Games. If a Library Asset is removed, Summer will notify Creators whose Games use it where practicable and, except where immediate removal is required (illegal content, malware, child safety), will provide a 30 day window to replace the asset before affected Games face enforcement for containing it. Licenses under Section 6.7 terminate prospectively for assets removed for infringement or illegality; Acquirers must remove such assets from their Games within the window. Copies of an Exported Game already delivered to end users before the removal are not recalled and stay outside this prospective termination; the Acquirer's duty is to stop further distribution of the removed asset and to remove it from new builds and new copies of the Exported Game within the window.

9.5 Automatic credit on removal. If moderation or a takedown removes a Shared Asset for which an Acquirer paid Sparks, Summer automatically credits the Acquirer's Account with the Purchased Sparks paid, as the Refund and Billing Policy describes, and reverses the related Earned Sparks credited to the uploader; amounts already paid to the uploader are recovered only by netting against future Earned Sparks and Program Payments, never from a bank and never from Purchased Sparks, except in cases of the uploader's fraud. Where the removal is a takedown under the notice process in Section 9.2, the Acquirer is still credited at removal, but the related Earned Sparks credited to the uploader are held, not reversed, until the counter-notice window under 17 U.S.C. 512(g)(2)(C) closes; if the asset stays down the held Earned Sparks are reversed, and if the asset is restored they are released with their original maturation dates and Summer bears the Acquirer's credit from its own funds. This hold is dormant while Shared Assets are offered at no charge.

9.6 Enforcement against uploaders. Enforcement follows the Summer Games Terms of Service, including warnings, feature suspensions, Account suspension and termination. Summer will not lock an Account solely because a charge is under dispute.

10. Indemnity

10.1 To the fullest extent permitted by law, you will defend, indemnify and hold harmless Summer, its affiliates and their officers, directors, employees and agents, and each Acquirer of your Shared Assets, from and against any claim, demand, loss, liability, damage, cost and expense (including reasonable attorneys' fees) arising out of: (a) any Shared Asset you upload, including Summer's exercise of its rights in it; (b) your breach of the warranties in Section 8; (c) any claim that Summer, an Acquirer or a Player owes any fee or compensation to a third party in respect of your Audio; (d) your violation of an Upstream License; or (e) your removal of, or interference with, an Attribution Manifest. 10.2 The indemnified party will give you prompt notice, and Summer may at its option assume control of the defense and settlement of any claim against Summer, in which case you will cooperate at your expense. You may not settle a claim in a way that imposes obligations on Summer or an Acquirer without prior written consent. 10.3 This Section supplements the indemnity in the Summer Games Terms of Service. If you are a consumer, nothing here expands your liability beyond what applicable law allows.

11. Disclaimers and liability

11.1 Library Assets are provided by their uploaders and upstream sources, not by Summer. Except for Summer Assets, Summer does not create, inspect or verify Library Assets and makes no warranty about them, including quality, safety, fitness, non-infringement or the accuracy of license metadata. All Library Assets are provided "as is" and "as available". 11.2 The limitations of liability in the Summer Games Terms of Service apply to the Asset Library and these Terms. Nothing here limits liability that cannot be limited under applicable law.

12. Term, closure and portability

12.1 These Terms apply whenever you use the Asset Library and survive for as long as any license granted under them remains in effect. 12.2 Portability. Consistent with Section 15 of the Summer Games Terms of Service, you may keep copies of your projects and export them in a Godot-compatible format, including on Account closure or Platform wind-down. Exports include the Library Assets embedded in your projects to the extent your licenses permit (the Standard Asset License permits this under Section 6.3(c) unless the asset is Platform only; Upstream Licenses control for Third-Party Imports), together with the Attribution Manifest, which must remain intact. 12.3 Sections 4, 6.7, 7.5, 7.6, 8, 10, 11 and this Section 12 survive termination of these Terms or closure of your Account.

13. Changes and contact

13.1 We may update these Terms as described in the Summer Games Terms of Service. Material changes are announced before they take effect, and the version in effect when you upload or acquire an asset governs that upload or acquisition. 13.2 Contact: Summer Labs, Inc., 2810 N Church St, STE 89812, Wilmington, DE 19802, United States, support@summerengine.com.
