obj loader obj format or serialized object process help

[ghidra]

I was trying to import an obj, but it keeps crashing the app on load. Perhaps my obj creator is adding some superfluous data in there that I can strip out. Is there an obj file somewhere that is know to work?

or

Is there any progress on instructions to the process of using JPCT to serialize an obj?

Probably I would still have to write out a proper reading obj file for the serializing to work.

Thanks.

What's the log output for the crash?

[ghidra]

I will look into getting that for you.. when I am in front of it again.

EDIT:
So in the process of getting the logs, I found some mistakes, and managed to get the OBJ to load. But not to actually render. Now I am certain it is because my model isn't triangulated or something along those lines, user error.

But the logs did throw some errors.

It might as well be out of sight or you forgot to set some light. If you haven't already, clear the buffer with another color than black. That usually helps to find "missing" objects better.
