Awesome, that got me pretty far. For now, I just did a “hack” by attaching the 3d model to the guiNode and scaling it differently. However, now it is semi-transparent in some sense. Like, parts they shouldn’t be seen are seen:
It looks weird because some parts that are visible shouldn’t be.
I think I read something about this, but I don’t remember reading a fix. Does this have to do with orthographic projection?
EDIT: I just stumbled upon this thread which may or may not make things easier, I’m not sure.
EDIT EDIT: Is something getting culled by the camera?
