Shader-Only blended projection in 3ds Max
polycounter lvl 14
For a long time whenever I wanted to use blended box mapping or blended projection, I've always fallen back on Neil Blevins' Soulburn Scripts. But lately I was researching ways to do this in a shader alone. The following video demonstrates a setup for this to work with native Max functions without using any UV modifiers. I specifically built this to use with a Substance workflow that incorporates Allegorithmic's Bitmap2Material .
