It seems my Blender file I’ve been working on became corrupted. 😦 Luckily I keep regular backups of the file as I move through various stages, but I did lose quite a bit of the work I did recently as far as fixing some issues and poly reduction.
The good news is the texturing work I’ve done so far isn’t affected, so there’s that at least. But now I’m working to recover what I can and get things back to where I was. I really hate doing things over again. 😦 Things should be back on track in a day or two.
