RageGT: ALL mods are incompatible to v1.3, according to CDPR note on the patch page.
I actually did a fresh install because patch added so much stuff to /CookedPC that I couldn't know which were mod and which were new stuff from 1.3
I want that cool mod that makes Mage's Pants look like a plain BLACK leather pants working on 1.3 *sighs* ... way cooler! =)
I didn't install the patch yet, because I am waiting on the new version of CEO (and hopefully Better Combat), but logically, I am 99,9% sure that texture mods have absolutely NO reason to be incompatible - unles they suddenly changed texture format, which kind of equals a cold day in hell.
I hope you mean my magic pants mod (elder blood), which is not plain black, but dark enough and would make me feel flattered and I urge you to try them (you can always remove a texture file again without anything sticking). :)
Edit: Now I patched and I can confirm that my White Wolf mod, my hunter armor and my gloves and pants work beautifully. Also no problem with the Remove intros except CDPR screen, the alternate dice and the bag instead of book mod. I was pretty sure about those, other mods I will add back in one by one. No UI mods of course and at least some xml mods might need updating, depending on which files CDPR changed. You certainly won't have any problem with any file ending in .xbm.
