A constant problem for most people, including myself, is that some of Revan's robes files are also used for other popular robes. (example Darth Bandon's robes) Is it possible to have them both installed at the same time without them messing with each others files?

As this is a modding question moving to modding forum...

Also the reason this is so is that there is a limited number of body model slots available in the Kotor's, K1 especially so the Revan armor slot is the most obvious/convenient to use.

The slots are basic clothes and the various armors like 9 types and one jedi robe slot plus Revan's armor slot, that's it in K1. TSL adds one more robe slot, plus a rarely used space suit slot, and the dancers outfit slot. That's just from memory, there might be more or less it has been a while for me. ;)
