No, they work — you don’t want a mesh that includes eyes when deforming (the wrap only needs a head and body, or a combined base mesh if you want a perfect fit). You are going to have to separate your wrapped mesh after. But it is a messy pipeline. I’ve never gotten a mesh I export out working as a deform mesh — they all break regardless of what I do, but the two linked meshes work for some reason. there are a few thing you need to after the wrap, If you don’t fix the vertex order on , everything breaks. There is also a big problem with skinning for bulky characters ( im hoping epic can adress that) . Double-check that nothing was added — it needs the same UV, same polygon count, same vertex order. If you messed up the eyes, the problem is where your loops are After the wrap, smooth out edge loops around the eyes just in case you have stacked polygons. That would also deform the eye socket
When you place the markets this one works pretty good.
