I’m not sure if this is a bug because I did not test enough but maybe it helps someone.
I got a circulair dependency error when baking multiple textures into one on a mode. Al models had the selected unconnected “bake to” texture in their shader so no errors there. But I still got a circular dependency error messing up my new texture. So not only did I get the error but also a variety of materials did not baked their texture en turned blank.
After a long search I noticed a normal map was not on Non Color data on the material that gave me the circulair dependency error. I turned it to Non Color éh voila, it worked.
