I’m not an expert in this area but i’m also curious about this, it seems like an interesting approach. Besides performance i don’t see any disadvantages, but how would you implement it? If you don’t want to have modular skeletal mesh pieces, you’ll need to apply one UV texture to whole mesh - so for example to hide only legs, would you make some masked (in legs area UV space) material and hide only masked part? Or am i missing something?
