Is it possible to draw things in a loaded 3d model

say, I have an empty room 3d model (.3ds), I loaded it into my of sketch using ofxModelLoader. Since it’s an empty room, I want to draw things in this room. But It looks like it won’t allow me to draw things in it, as if the room is actually not empty, but a solid cube with a empty looking…

this should be no problem. It might help if you draw the model in wireframe to get a sense of how it’s constructed and if there’s something that might occlude what you are trying to draw.

also, this is a useful function to make sure that depth testing is enabled:

Thanks so much zach. The EnableDepthTest fixed it perfectly!!
