Trumble
What it is
Trumble is a browser-based creative suite for game developers and artists working on texturing and painting. The Texture tool lets users paint PBR textures on meshes in a 3D viewport, while Paint handles 2D editing for alphas, masks, and channels. Bake generates normals, ambient occlusion, curvature, and other maps in the browser without an offline renderer. Texture packs can be exported for Unreal, Unity, Godot, and Roblox. The Texture tool accepts OBJ, STL, FBX, glTF, and GLB files, and meshes need proper UVs to be paintable. Trumble includes hundreds of ready-to-use materials and textures and can connect to Google Drive to autosave projects there rather than using Trumble account storage. It runs in modern browsers on Windows, macOS, and Linux, with no account required to get started. Files and assets opened or imported are processed in the browser, and users retain rights to content they create or upload. The product is in early access. The free plan includes current tools and workspace ads; paid plans start at $5 a month.
