I'm going totally crazy. I have my nodes all set, the Vertex colors are named something other than 'Col,' and everything is ready to go for rendering. However, every guide on the Internet tells me to "Open the properties tab and check the Vertex Color Paint box." Without it, I won't be able to see my vertex colors in the rendering.
Does this box even exist in Blender v3? I have looked EVERYWHERE for it, up and down. I got excited because there was a similarly named option under Bake. Is baking now the only way to see vertex coloring in a render? Am I missing the feature somewhere? Please help me! I just can't seem to get these colors to correctly show in the render. It's worth noting the base colors and blushing are part of the same vertex color set, in this case 'Skin.'
EDIT: Here's a screenshot of the final result. You can compare it to the preview version of the sculpt and see how, although basic colors render, a great deal of the blushing detail on the sculpt is just absent.
As requested, here are my render settings. I haven't touched anything at all, so far as I am aware.
Thank you to everyone replying! I hope we can figure this out, it's like the last thing standing between me and really feeling comfortable with Blender lol...until I find the next thing, anyway.
