I'm trying to import an OBJ file with multiple sub-objects for microvertex painting. Is there any way to subdivide only certain subobjects as I'm getting an unnecessarily high polycount on parts of the model where I don't really need it? Also is there any way to subdivide these objects further once the import process has been completed? I might be tempted to use per pixel painting, but I'm assuming that any bump information I paint will not generate a good ambient occlusion texture when baked to a low-poly through xNormal. Thanks in advance.
