Today’s tutorial teaches you everything you need to know about Cross-Polarization. The necessary hardware/gear, and why it matters. It is absolutely essential if you’re trying to scan an object that has a very shiny/reflective surface. Taking a look at the renders in Unreal Engine 5, it doesn’t take long to see the vast difference between the two approaches, the cross-polarized result is FAR superior. The scans done in this tutorial were made with RealityCapture.
