WhimTex

Unity Sprite Editor & Texture Editor

Quick texture ideas, right where you use them. WhimTex is a free, open-source editor for touch-ups, simple sprites and VFX textures directly inside Unity. Paint a particle mask, generate noise, combine images or try a new effect without interrupting work on your game.

Save an editable composition that works as a texture in materials. Enable Live Update to see changes in your scene as you paint, or export when you need a separate image.

Requirements and scope

Unity 6 (6000.0) or newer. WhimTex runs only in the Editor; use the saved textures and sprites in your game. Game Post FX preview is optional and currently needs URP 17.x with Universal Renderer. Other editing tools do not require a render pipeline package.

Creating an integration or writing shader code? The separate technical reference is for developers. See the changelog for changes and acknowledgements for third-party sources and licenses.
