I’m getting the following error and seems to resolve when I disable some layers (right now I only have 5 total)
[SM5] /Engine/Generated/Material.ush(19891.2-41): warning X3206: implicit truncation of vector type
[SM5] /Engine/Generated/UniformBuffers/Material.ush(41,14-41): error X4510: maximum ps_5_0 sampler register index (16) exceeded
