Hello. This mod (https://www.nexusmods.com/dragonage/mods/6051?tab=description&BH=0) lets you install standalone resources from the mod Improved Atmosphere, infamous for its compatibility issues. I chose to download the pack that changes Irving's robes, but upon starting a new game, his body is invisible despite not using any other mods that alter or add armour or clothing sets. I HAD one, Viva La Orlais, but I deleted it before installing this one. Maybe there are residue files somewhere on my computer but so far I haven't found anything. The only other mod I have that deals with .gda files is FtG UI Mod - More Readable Fonts and Interface but I find it an unlikely culprit...
Notable mods I am using: DA Redesigned, Qwinn's Ultimate Fixpack, Large Address Aware patch, Redefine Your Hero's Voice, and some hair and face texture mods. I am playing through the EA launcher if that's of any importance, Steam made the game act funny sometimes.
Enjoy the rest of your Sunday and thanks for reading!
