[SM5] /Engine/Private/VolumetricCloud.usf(118,33-53): error X3018: invalid subscript 'VertexId'
This is happening in VolumetricCloud.usf, but it seems that I can avoid the error by adding the following line. # // Force inclusion of VertexId FVertexFactoryInput even if not otherwise required

  1. #define PASS_NEEDS_VERTEX_ID 1
