Incorrect results are being produced from the NRM packing. The current algorithm does a simple value copy but to maintain comparative visual equality we need to renormalize the normal values and also compute roughness from normal variance.
Repro steps: Input Normal texture:
Input Metallic Roughness texture:
Expected NRM texture:
Actual NRM texture:
