Could this be done in Blender?

I would like to see a similar plugin for Blender. Vertex painting hasn’t changed in 10 years - in fact it peaked at 2.49 and has seen a steady decline since then. Anyone up for the challenge?

It looks like a major issue is that “color” is defined in Blender as RGB with no A component.

I have never made a plugin or done anything with Python, but I’m going to give this a shot. I’ve been waiting around for someone to work on this but no one has taken it up. If you are familiar with python and have some ability I would be happy to work with you developing the vertex features from an artist perspective.

One thing I found recently is the the script “Bake UV-Texture to Vertex Colors” written by CoDEmanX. This is a step in the right direction for sure.

Ideally the plugin would treat each RGBA channel as its own layer.

*** edit

another useful script is the color palettes script that is included with Blender. When you are vertex painting you are usually only mixing pure colors
