Not so, I fear: here is a screen shot from my Poser 4.03 operating under Windows 2000 Professional, when I try to open a reflection map from the materials dialogue. The two .pct reflection maps are definitely in this folder, but despite the file type saying "all files", only the .jpg versions are visible. Note also that .pct does not appear anywhere in the file type list. This Poser install just does not acknowledge the existence of .pct files at all: the same thing happens from any other 2D image opening dialogue. Incidentally, "all files" seems not to mean all files as it does in other Windows file open dialogues - try any file open action from Poser, and you can never see every file type in a folder. This may have some bearing on the fault; any Mac users care to chip in?
