Here is a video of a light baking asset filter in MiniOrk (which called into NVidia’s Gelato API). There is no actual color texture other than the baked subsurface scattering lightmap. It could also bake to vertex colors. You could bake almost anything you wanted that Gelato supported. I have since moved away from Gelato since it was buggy, inefficient at baking, and is no longer supported. I had replaced Gelato at one point with the open-source Pixie and also had similar troubles with it. I am currently working on my own renderer with baking as a high priority focus, you can see progress on that here .
