I need to modify a UE4 usf vertex shader (GpuSkinVertexFactory.ush to be specific) to add functionality to the Apex Cloth Skinning parts. I already have the desired behaviour working using CPU Skinning, but CPU Skinning becomes a bottleneck very quickly with many skinned meshes.
If that’s something you can do, drop me an email: ujen@vicogamestudio.com
Happy to provide more details via email.
