The wiki page says vertex colors are supported “You can access vertex colors (using the color output)”. Which color output is meant? I tried the shader data node to no avail. Uniform.hx only talks about light colors. I´ am left clueless.

You need to use the Vertex Color node in the shader editor.
Here’s an example file:

Worked, after finding out where to set a hook. After setting it i was able to select “col” in the vertex shader node (Note: add from input section).
