Yeah, it'll do a .dbo. It actually takes whatever format and ultimate converts it to .dbo internally anyway. Sometimes it converts to .x (for .3ds for example) as an intermediate step.
I found (although I haven't tried) that you can save .x files with dbSaveMesh(). Otherwise, the dbSaveObject() command just saves to .dbo as far as I know.
I've noticed that a popular format .obj is open and text-based. That would be a nice format to add!
Judging what we see is the greatest blinder and self-limiter in the universe.
What we perceive is never reality. It is only a story we tell ourselves based on our current perspective, which has far more to do with our beliefs about ourselves than with anything else.
