ConstantProjection (DX11.Effect) “projects” on both the front and back sides of an object. There is a DX9 version, ProjectedTexture (EX9.Effect) that has a front face-only input pin to toggle this behavior.
Seems like I figured this out in the dim past, but maybe I’m just thinking of the DX9 version. Is there a way to do this in DX11? I looked at the code in the DX9 shader, which is a very simple conditional:
//show only if projection comes from the front if (FrontOnly) if(input.angle.x < 0) col = BorderColor;
but no idea how to do something similar in the DX11 ConstantProjection code. Athankew!
