Blender Crashes when Baking High Resolution Textures "Circular Dependency" error I have a high poly (1,3 Mio faces) photo scanned mesh with 17 generated 8k textures (totalling 500 MB)

All the texture are looking something like this one here:



My goal is to bake those 17 diffuse maps into one single 8k texture. But when I hit "Bake" I first get some errors, which look like this:

Circular Dependency for image "texture_xy" from object "xyz"


and then Blender crashes.



First of all I want to know why those errors occur. But I am also concerned, that Blender doesn't crash because of the errors, but rather because those textures are just to massive in size.

Any suggestions on techniques I can use to bring those 17 textures into 1 single texture?
Would it help to decrease the polygon count of the mesh?
The issue was just that I did not have sufficient memory. So I had to downscale the high resolution textures to make it work
