What's inside

Everything in one tab.

Trumble brings the full game-art texturing pipeline to your browser. No heavy software, no licence fees — just open and create.

3D Viewport Painting
Paint PBR channels directly on your mesh in the 3D viewport. See roughness, metallic, and normal maps update in real time.
2D Texture Editor
A lightweight image editor for creating and editing textures and alphas. Paint, adjust, and save directly to your asset library and use them across all your other tools.
In-Browser Baking
Bake normals, ambient occlusion, curvature, and more — all in your browser with no offline renderer setup needed.
Huge Built-in Material Library
Hundreds of ready-to-use materials and textures included. From metal and wood to fabric and stone — drag and drop onto your mesh.
Workflow

From mesh to engine in four steps.

01
Import your mesh
Drag in any OBJ or FBX with clean UVs from Blender, Maya, or wherever you model.
02
Bake your maps
Bake normals, AO, and curvature in the browser. No third-party baker required.
03
Paint and layer
Add material layers, paint detail, and adjust PBR values directly on the model.
04
Export to engine
Pick your target engine and download a ready-to-import texture pack in seconds.
