Baking Scultpy Issues.

I can’t seem to get Blender to behave consistently with regards to baking sculpt meshes. I’m following the process correctly as I understand it but sometimes I get a blank image or Blender just hangs. Other times it works ok.

In some instances, all I’m doing is manipulating points in edit mode without adding extra levels of detail. But after creating a new image in a new UV window and baking the mesh from the edit view selecting ‘all’ it doesn’t always work.

What should I be doing? What should I not be doing?

Thanks

Here’s a very basic baking just moving points but the same method as with a high poly sculpt of baking normal maps.
