Vertex colors not baking to image on this specific model

vertex colors not baking.blend (176.4 KB)

Vertex colors simply not baking. I created a new object and was able to bake vertex colors just fine. What is wrong with this specific model?

In your model the UV map is NOT OK. One face is covering all other faces.

You need open the UV making the faces not overlap.

The bake process paint the colors in the texture following the UVmap, if the faces overlap in the texture the result is the last color painted. In this case the black color. But after you open the UV in the right way all work ok.

How did you figure that out? Seems like a difficult thing to spot. Did you run into this issue before?

Yes. I’ve been working with Blender for years and over time you get used to the steps involved in 3D production.
