Hi sir, did you manage to bake a metahuman facemesh into VAT? Here’s the problem I encounted: I want to bake my own metahuman face mesh into VAT, but when I convert the skeletal mesh of this MH face mesh into static mesh, I found there’re 9 material slots in it (excluding slots for lods), which is same with the number of slots in its skeletal mesh. But there’re only 2 slots in static face meshes from the City Sample. Do I need to export my skeletal mesh into some other 3D softwares to reorganize the slots to match the example from the City Sample or this really doesn’t matter, I just should bake every of these 9 material into VAT? Looking forward to your answer and thanks in advanced.
