Why does my materials not show in a bake? I have a model with various materials assigned. I want to bake all these materials into a texture. It seems that only very few are actually being baked to the image.
My Settings

Cycles
Bake Type: Combined
All boxes Diffuse, GLossy, Transmission.. etc are ticked
I have a UV Unwrapping (Done by smart UV unwrap)

I hope someone can help me answer to why the result is as it is, and what I can to get a result with all the color?  am planning to do a metallic map, and a normal map as well (TIPS appreciated). The model will be export to Unity.

Image of the bake result and the model (rendered in material preview mode)

Here is an image from solid mode ( when you press z)

I fear that the materials may be compatible, so I will attach some images of those as well. They are all free assets available through BlenderKit.com and their plugin for blender.
From looking at the photo of the graph, the &quot;combinedbake&quot; node should be changed from &quot;single image&quot; to &quot;generated&quot;.  Add that node to all materials being baked.
