MeshCoat vs Trumble

MeshCoat is free 3D texture-painting software for game developers and 3D artists. It runs on Windows, macOS and Linux, operates locally, needs no account or subscription and loads textures from folders on disk. Brush strokes are mapped from 3D camera space into UV coordinates in real time with hardware-accelerated shaders. A non-destructive layer stack supports hiding, reordering, opacity changes, duplication, merging and live blending. Tools include brush, stamp, eraser, fill bucket, effects brush, eyedropper and face selection. Edge-wear and crevice-dirt generators provide real-time previews with colour presets. A screen-space stencil displays reference images for painting or decal projection, and a texture shelf browses local PNG and JPG files. MeshCoat imports OBJ, GLB and glTF models and exports composite maps as PNG. The maker says composite results update at 60 FPS, with 100-step undo and redo. The app is in development, contains no telemetry or network calls, and has no runtime AI or machine-learning models. It is licensed under GPL-3.0-or-later and accepts optional contributions.

Trumble is a browser-based creative suite for game developers and artists working on texturing and painting. Its Texture tool paints PBR textures directly onto meshes in a 3D viewport, while Paint handles 2D work on 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. The suite includes hundreds of 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; no account is needed to get started. The product is in early access and receives regular improvements. Free includes current tools with workspace ads; paid plans start at $5/mo, with higher tiers adding options such as no ads and early access.
