Actually, OZ only handle a few of 3DS properties, so, you can forgot about most of the 3D l33t technics (BumpMap, NormalMap, ...). I know OoW / DoN zones/models use them, but as its new EQ format, i have no idea if it can be integrated to OZ zones (which are S3D).
As for the dimensions used in EQ, so far, i can say that 4mu = 1m (yeah sorry im european and use meters ...). Personally, i use a cube of 8mu/2mu/2mu as character reference to check size of objects in my zone.
