Form loads OBJs in the size and resolutions in which they were created. If you imported an OBJ and it doesn't seem to appear, check that:
- Your particle size and dimensions of the Form layer are scaled properly for the size of the composition you're working in. Try adjusting these parameters to see if your OBJ then shows up
- Your OBJ is compatible with Form. If an OBJ has negative space, or was created with from an incompatible source, it won't load into Form. Try adjusting your OBJ model or creating it from a different source to get it to load properly.
