I've decided to make skins but ive quickly run into a problem
From this website : http://primalcarnage.com/devwiki/index.php?title=Extinction_Editor_Skin_Creation --Ive found out how to make skins (although it's still confusing kinda ??? gotta read it over a bit more I guess) and I tried to download blank bases from the "character asset resource pack". When they have finished downloading I went to look but none of them were pictures ?? I didn't see any bases all I saw were unopenable FBX and TGA files. I'm kinda new to all this and I have no idea what those are.

Secondly, how exactly do you upload things onto the Workshop ? I've looked and I couldn't find anything that allowed me to upload anything ?

I might have more questions later (since im downloading the SDK right now) but these are my biggest issues

Thanks in advance if a dev happens to see this !
