I don't know if this is the right place to ask for request but please send it to right thread if not.
Almost all diffuse map have an alpha when it comes to game models. I always need to manually copy the diffuse to opacity, enter the settings and tick off premultiplied alpha and then in the mono channel output go from rgb intensity to alpha.
This is done on almost all models, especially hair textures and often body.
I think chrrox sent me a script once but would be nice to have it automated with umodel
This is what the listener is giving me:
meditMaterials[1] = $.material
meditMaterials[1].material1.opacityMap = Bitmaptexture fileName:"M:\TERA\S1Game\CookedPC\Art_Data\Packages\CH\Castanic_F_R\Texture2D\Castanic_F_R13_Body_diff.tga"
meditMaterials[1].material1[#Maps][#Opacity__Map__1__Castanic_F_R13_Body_diff_tga].preMultAlpha = off
meditMaterials[1].material1[#Maps][#Opacity__Map__1__Castanic_F_R13_Body_diff_tga].monoOutput = 1
