Transfer color attribute R, G, B to unique vertex groups

[PieBaron]

Hello, I recently learned how to bake my material (curvature map) to color attributes, but the addon I’m using needs a vertex group for scattering / distribution of objects.
I was thinking to pack different maps to R, G, B, bake them, then somehow convert them to vertex groups, anyone have some tips?

I saw in an older post someone suggest to bake to texture, but I wanted to check if there is a more direct method in v3.2.0

There is addon that can do taht:

Vertex Color Master

I made an add-on that is designed to help make working with vertex color data a little bit easier. The main feature of the add-on is the isolate workflow, that allows you to isolate one particular channel of color data and work on it with all the normal tools. There are also tools to help you move data between channels and between different data types, so you can transfer color to weights, weights to color and even use UV data as well as copying and swapping individual channels of color data. F…

ot that way

Thanks so much, I see now I can do everything in geo nodes, no need for baking / dealing material stuff.

Awesome that this can easily be done with geonodes now!

My addon was originally made pre-2.80, and although I did port it to 2.80+, it hasn’t been updated for quite a while now. With the latest changes in 3.2 and 3.3 to how vertex color information is stored, it looks like the addon will break, and I’ve been a bit too lazy to update it I think people are better off sticking with geonodes for now.
