I love Gaia's outfit but that coat....well I love it more so I updated the materials with new textiles!
IMPORTANT NOTE: The velvet texture is taken from the Roseblood Coat (Hence the red default coat color), despite this square doesn't have a dye template that allows for the velvet's particular diffuse/specular settings. The specular being heavily saturated is what creates the velvet-like shine. So I recommend that if you want to keep the velvet texture but change the color, to instead edit the colors though glamourer's color-setting (8A/8B rows) or directly editing the colors in the mods "advanced editing > materials > #08", keeping the saturation/shade the same but changing the hue SHOULD keep the velvet vibe.
Using glamourer's dye slots in the design settings will potentially remove the velvet texture, I haven't tested this with that many colors.
There SHOULDN'T be any huge problems, but I am still a novice modder so if there is lmk on discord and I'll see what I can do!
