I am working on a vfx creature for a movie, and I've run into a very specific issue. I haven't found anything on any forum that helps fix this issue.
I modeled and rigged a topology version of a hires sculpt, and everything was working fine. When I began the materials for the creature, I baked an AO map from the hires to the topology, which also worked fine. Then I baked an AO map from just the topology onto a separate texture in the hopes to blend the two. It baked successfully, but shortly after blender crashed.
An autosave file was available and would take me back to just after the second bake, and any command or change related to the topology object caused blender to crash.
Further, I can append every other object to a new blend file, except "Plane" the topology object (bad habit of not naming I know). This single object cannot be accessed or changed, and the autosave file has since been crashing on startup along with the original file.
I've tried opening the file on a different iMac, no luck. Changed to a different version of blender, still no. Every tip and trick and workaround to a blender crash has also not worked, I am out of options.
I am in dire need of this object, sweating heavy bullets here. If anyone can help me figure this out I am getting you a credit on this movie.
Below is the crash report saved in the /tmp:
