I hadn't noticed this, but I didn't really test it in-game very thoroughly with all the animations. I'll check it out.
I had started to re-create some of those Combat Suits after I upscaled all the vanilla textures, but I hadn't finished them all yet. I'll try to get back to it someday and provide all new 2048x2048 versions. I can check out the Czerka texture then. I would hope that I had fixed the UVWs already in my new 4x mod, so that the old 512x512 textures should work with the new models. There's always room for improvement.
There are a lot of little changes and fixes, both UVW & texture, that I didn't specifically point out in the screenshots. I spent months trying to clarify all the changes, both in screen shots and in the text in the spreadsheet. I didn't want to spend even more time trying to catalogue everything. I'm glad that you noticed though. I also texture fixed the shoulder seam on the female rags, but didn't document it.
For the most part that previous Party model fixes is either duplicated or improved upon by this new 4x mod. The old mod is still required for the Bastila head texture. The 4x mod supplies a 1024x1024 upscale that is faithful to the original art style; just the seams have been fixed; and added the transparency on hair and eyelashes. The old party fix mod supplied a 2048x2048 texture that adds a lot of photo realistic detail. I do plan on combining my Party model fixes with my old K1 underwear mod and upscale everything as well. I'm just adding some photo real details to Mission's head texture right now. I might do the same with the male party members. Once that's done, both of those old mods will be obsolete. Juhani Catlike Head will remain a separate mod, but I'll upscale that as well.
I hadn't seen this mod before, as I've only had time to work on my own stuff. No time to check out the great work by other modders here. I like this mod's Mission armour models being resized for her. I haven't done any adding of backfaces like that mod does. I've only been editing the existing UVW & XYZ coordinates using Taina's Replacer tool (which can't handle adding or subtracting polygons). I hear there have been some nice improvement to tools for compiling models from Blender, but I've never used them. Hopefully someday I will have some free time to give it a try.
You can always try mixing and matching PapaZinos' models with my 4x textures. Maybe they will be compatible enough.
