Obviously, the bigger an imagemap, of whatever sort, the more RAM gets used. But what happens if the same imagemap is used multiple times, such as two figures wearing the same uniform? Does anyone know if Poser stores just the one copy in memory?

That appears to be the case AntoniaTiger, provided the file paths to load the imagemap are identical, If you load a second figure of the same type which already has texture imagemaps specified, a second copy of the map is not loaded. You can verify this in P4 or P5 material room by looking at the image map list before and after loading a second figure. The list doesn't change. In P4, you also couldn't load another texture with the same name (in case you were modifying a texture and trying it out) - very frustrating. P4 would just keep using the one loaded and had no way to unload textures other than stopping and restarting Poser.

Thanks. P5 still seems to have remnants of that texture-name problem. I've come across problems when two textures have had the same filename, although in different folders, even though textures can be edited and reloaded without apparent problems.
