Trumble

Trumble is a browser-based creative suite for game artists and developers who need texturing, painting, baking, and engine exports in one workflow. It is best suited to people working with UV-ready meshes who want to avoid installing desktop software. The free tier is unusually broad, while workspace advertising and early-access status are the main compromises.

Overview

Trumble combines 3D PBR texture painting, 2D texture editing, map baking, and game-engine export in a modern browser. That makes it a practical hub for routine asset preparation rather than a single-purpose painter. The product remains in early access and receives regular improvements, so its capabilities are still developing.

It runs on Windows, macOS, and Linux through a modern browser, with no account required to begin. Files and assets opened or imported in the app are processed in the browser, and users retain rights to content they create or upload. Projects can auto-save directly to Google Drive instead of consuming Trumble account storage. Meshes must have proper UVs before the painting workflow can work, which is an important prerequisite for anyone importing models.

Key features

• 3D texturing: The Texture tool paints PBR textures directly on meshes in a browser-based 3D viewport. OBJ, STL, FBX, glTF, and GLB are accepted, giving it useful format coverage, but UV preparation remains the user’s responsibility.
• 2D painting: The Paint tool edits textures, alphas, masks, and channels. It complements mesh painting when a channel needs targeted adjustments or a texture must be edited outside the 3D view.
• Browser baking: Bake generates normals, ambient occlusion, curvature, and other maps without an offline renderer. Keeping this step in the same workspace can simplify a small asset pipeline.
• Engine export: One-click exports format texture packs for Unreal, Unity, Godot, and Roblox. That is especially useful for artists moving assets between those four ecosystems, although the product currently has no procedural-material feature.
• Material library: Hundreds of ready-to-use materials and textures span metal, wood, fabric, stone, and other categories. They provide starting content for projects rather than replacing custom authoring.
• Storage and roadmap: Google Drive integration handles project saving outside Trumble account storage. Planned work includes procedural materials, Google Drive project storage, a trim-sheet tool, more bake-map types, and additional export presets.

Pricing

Trumble uses a freemium ladder with a permanent free option and no free trial. The Free plan costs nothing, billed at $0 forever, and includes all current tools and all future tools in a browser-based workspace with ads. It is the right starting point for learners and occasional artists who can accept advertising.

Low-Poly costs $3 a month, billed $3/mo. It includes everything in Free and supports ongoing development, but the published benefits do not remove workspace ads or add a different tool allowance. Pro costs $5 a month, billed $5 / month, and adds no ads plus a full workspace layout; it is the clearest fit for regular users who want a cleaner working environment.

Mid-Poly is $8 a month, billed $8/mo, with everything above and the ability to vote on roadmap features. High-Poly is $20 a month, billed $20/mo, adding early access and direct developer feedback. Those upper tiers suit contributors who want influence or closer contact with development, not users seeking a larger published asset quota. Billing is handled by Trumble’s payment processor, which does not store card details directly.

Platforms

Trumble is available on the web, Windows, macOS, and Linux through modern browsers. Its no-install delivery is valuable on machines where desktop software deployment is inconvenient, while browser performance and the requirement for UV-ready meshes remain practical considerations.

Who it's for

Choose Trumble if you are a game artist, developer, or learner who wants one browser workspace for PBR painting, 2D channel work, baking, and exports to Unreal, Unity, Godot, or Roblox. The Free plan also makes it suitable for experimentation without a subscription. It is less suitable if you need procedural materials today, dislike ads, or routinely work with meshes that lack usable UVs.

Pros and cons

• Pros: Free access includes all current and future tools; browser operation covers Windows, macOS, and Linux; baking, painting, and engine exports share one workflow; Google Drive auto-save avoids using Trumble account storage; imported content is processed in the browser and remains owned by its creators.
• Cons: Free workspaces contain ads; mesh painting depends on proper UVs; procedural materials are not currently available; early-access changes may affect priorities; support response times may vary.

Alternatives

3D Texturing Software is a broader category starting point when you want to compare several texturing applications. Mixos Paint is a freemium, cross-platform option with Android and iOS support, but its free tier limits cloud storage, AI credits, 2D viewing resolution, and exports. Surface Labs is free during early access and supports Android, iOS, Linux, macOS, and Windows.

InstaMAT offers a free Pioneer License for qualifying projects with attribution and a paid Pro License at $36 a year. Marmoset Viewer is a free viewer included with Toolbag versions 2.07 and newer, with standalone availability. AwesomeBump is free and open source with no paid plans or usage limits stated. LigidPainter is completely free and listed as name-your-own-price.

Mari provides a free non-commercial plan with 4K and 16-bit export limits and disabled Python scripting, while Material Maker offers a name-your-own-price MIT/CC0 distribution and a 14.99 USD one-time Steam version.

Verdict

Trumble is a strong choice for artists who want a no-install, browser-based path from UV-ready mesh painting through baking and engine-formatted exports. Start with Free to access the full current toolset, or choose Pro when ads and workspace limitations interfere with regular work. Look elsewhere if procedural materials, a mature non-early-access product, or workflows that do not depend on proper UVs are essential.
