Documentation: Flowmap Plus Doc

Flowmap Plus is an in-editor tool for painting flowmap textures on a 2D canvas.

No external apps, no scene setup, no mesh dependency.

Open the Flowmap Plus panel, paint your flow direction, preview the animated result in real time, then save the final flowmap texture back into your project.

One canvas, direct flowmap output

Flowmap Plus writes flow direction into the texture channels used by Unreal flowmap material functions. Paint, erase, blur, pinch, inflate, or create vortex motion directly on the canvas, then export the result as a texture asset ready for your material.

Live preview while you paint

Preview the flowmap effect immediately with a built-in shader preview. Use the default engine diffuse texture or open your own preview background texture, adjust tiling and flow speed, and inspect the result without touching the current level.
