Could you try painting it in the Image editor instead? May be easier to paint it on the UVS directly. In the image editor go there and change it from “view” in the top left to “paint” and then find the uvs for inside the mouth and paint on them. LMK if that helps
I can’t find the paint option where is that
Were you able to get it?
no it’s not working I’m not able to paint on it, It’s in black
If you hit the N key you can get the brush settings and then zoom into the UVS. You’ll be painting on top of the UVS and grids that are there with the color you want. Just need to find the UV unwrap for the inside of the mouth and paint on that
oh I got It appears only on the main object, thx It worked
