I found this answer by Nathan: Weight paint in cycles nodes?

This is exactly what i want to do: use vertex weight value for "changing colors"/"use in shaders".

Nathans answer seems to be the solution, but...i don't understand it and i don't know how it works. Can somebody give me a step by step tutorial how to do it?

  • $\begingroup$ I'll leave it for a while to see if @Nathan is around.. that's only polite :). In the meantime, I assume you've already seen this $\endgroup$ Jun 25 '21 at 9:07

    $\begingroup$ maybe you should put a comment under his answer and ask for some precisions? $\endgroup$

    $\begingroup$ @Chris I'm sure it's nothing personal.. Nathan is probably looking for a specific query to answer: with the description already given, it's hard to know what to clarify further... there are quite a few possible gotchas. In the mean time, here's a blend file $\endgroup$ Jun 26 '21 at 10:17

    $\begingroup$ I got it working now with your geometry nodes solution ;) my main problem was - it works only in cycles and i always tested with EEVEE 🤦‍♂️ but MANY THANK YOU AGAIN AND AGAIN for your blend file. -> good idea to write the explanation in the text file, especially for me, who doesn't know what I did last week...😱 $\endgroup$

    $\begingroup$ ok, i now try to understand Nathans solution - because it works in EEVEE. Rendering in cycles needs days for what i am looking for....😱😱😱 $\endgroup$
