Flow Brush

Flow Brush is a Cinema 4D plug-in that adds a custom sculpting brush. The Flow Paint Brush allows you to paint texture coordinate offsets into vertex color tags. These offsets can be used to distort textures and add directional blur through the Redshift Blur OSL shader.

Several of the sculpting brush features are adapted for this brush. Here's a list of some of the brush features:

• Hold Control while painting to reset the vectors
• Hold Shift while painting to smooth the vectors
• Steady stroke for smooth curves while painting
• Interactive brush resizing and adjustment of strength
• Line draw mode for creating straight lines

The values being painted into the vertex color tag represent coordinates. It is important that you are either using a Linear input color profile or the new OCIO color management in your Project Settings, otherwise the values will be gamma corrected as though they are colors.

This is a small plug-in that is provided as-is. Feel free to share suggestions or bugs but I can make no guarantees of support.

Tested and working in Cinema 4D versions 25 through 2023.2.

NOTE: There is a known issue where the viewport preview of the vertex color tag will not update on objects that have 10,000 or more polygons. The vertex color data is still being updated and will affect the render.
