Subsurface Profile material?
Getting these errors from the 4.11p1 installed from the Launcher. It’s a Subsurface Profile material
MaterialEditorStats:Error: Error [SM5] DepthOnlyVertexShader.usf(140,29): error X3018: invalid subscript ‘EyeIndex’
MaterialEditorStats:Error: Error [SM5] BasePassVertexShader.usf(86,29): error X3018: invalid subscript ‘EyeIndex’
UPDATE: Subsurface Profile shading model was not the issue. It turns out all tessellated materials expose this bug.
UPDATE2: Above errors are from a copy of an existing project converted to 4.11p1. I tried a blank project with starter content. Enabling on existing or new material doesn’t lead to the shader compiler error messages above, but it simply doesn’t render. E.g. turn on on starter M_Chair material -> no error message but the chair is invisible.
