For VR Developers having this problem and cant disable forward shading, just download the textures and make your rig then switch the LOD to a higher setting the skin comes back. Chances are if you’re developing for VR you want a higher LOD off rip anyway. Otherwise the forward shading option people are bringing up is the correct fix its what bugged mine in the first place.
thinks!!!
I had the same issue here, only face was turning gray when I close up
basic issue is that my face skin for lod 0 and 1 is gray,
solution is that, I have changed forced Lod and min Lod to 2 instead of -1 or 0.
better solution is that changing gray skin into actual face but I need real quick solution so here is what I did.
One year later, even in 5.7 the face textures at LOD0 and LOD1 are not created when using Directx11. Im not sure if its a bug or a limitation issue by dx11 but there seems to be no mention of this. Directx12 is slow and i hope we see a future release fixing dx11 issues with metahuman.
