I know DR can export into OBJ, but I recall it exports brushes as split planes. Is it possible to add option to export brushes as convex manifold meshes (so that level in OBJ ends up being made of multitextured cubes/parallelepipeds) ? Is it also possible to export patches as meshes (or as patches, if OBJ supports them) ? Is it possible to export lights, entities, etc. as dummy/empty objects (or cubes of a small size) with specific name conventions ? (it would be easier to find them in 3D app) Thanks!
