I don't see any images...
Anyway, you probably have a corrupted model. Or you're on a Crapple. Or something else.
So, first step is to check if you have any custom models. If so, you can still manually delete them from the object list (changes still take effect even if nothing renders) and then reboot Whitehole. Are you using 1.4.3?
If I made an SMO level editor, would you use it?
