'the rsr in the geometries folder is a poser interpretation of the model and shouldnt be removed unless it become corrupted' Actually, it doesn't matter, it will just take longer to load the first time because Poser will rebuild it. However, it need not become corrupted. There are lots of reasont to kill those pesky geometries RSRs: If you remap the Object in UVMapper or anything else, you need to delete the RSR. If you change the OBJect in a modelling program of mesh refiner, you need to delete the RSR. If you don't Poser will ignore the cnanges and just use the RSR version of the OBJect. Also, if you distribute things, don't include the geometry RSR. It's pointless. On the tutorial for using p3Do Explorer: One thing to note: You'll notice that the RSRs created by Poser are just the objects, no background unless one is loaded as an image. The tutorial doesn't mention this, but the PNG thumbnail has an alpha channel which determines the transparency mask used in the thumbnail. If you select out th background colour and blacken that selection in in the alpha mask, the converted RSRs will also have the alpha masking -- and more importantly, you will get the drop shadow effect that a Poser-made RSR without a background has. You may or may not want this, of course.
