Mesh override texture

how can i have a modded mesh override shirt with custom texture but keep the character’s skin texture as well in the places where override metarial texture has transperant spaces?

what i want is a custom made model that overrides the vanilla one but it’s material/texture should cover the model like the normal vanilla shirt/pants material/texture overlays character’s body

I dunno how to do that, but I moved this thread from #modding:modding-discussion to #modding:modding-support

Are you talking about the “Character Mesh Replacement Test” item? (ID: 1522)? It turns your character into this
