Getting with 4.13 Preview 1 and 2 error when I am trying to use Tesselation:
Error [SM5] Material.usf(1542,2-16): warning X3206: implicit truncation of vector type
Error [SM5] MobileBasePassVertexShader.usf(35,3-43): error X3000: unrecognized identifier ‘FForwardShadingBasePassInterpolantsVSToPS’
with 4.12.4 and 4.12.5 (all version - thanks for that work very much :)) I don’t have that problem. Neither does it happen in the official 4.13 Preview 2 (Preview 1 not tested).
