How to bake vertex painted blend material to textures?

This is a blend material that I’ve painted with “paint vertex colors” in modeling tools.
How can I bake this to a texture?

What you see there is just the blended albedo map.
I’ve sent this blended albedo map on the emissive channel material attribute (I can do the same for all others maps to work on one texture at a time).

Baking it with “render target” doesn’t take care of painting on vertex.

Obviously “bake materials” wont’ work as it doesn’t take care of vertex paint too.

Is there a way to grab this as it is? (something like taking a screenshot on what I see on that rectangle)
