Hmmm...

Zv = ABS(Zc) ...renders completely black!

Not what I was expecting, but it explains just about everything! It looks like the Z Component output of my XYZ Components brick is already in camera-space, with forward-facing normals having negative values. Time to try my combining normals network again.

Thanks Richard and millighost!

(In my defence,  I was absolutely convinced that the brick preview renders for float values showed black for negative values!)


The 3Dcheapskate* occasionally posts sensible stuff. Usually by accident.
And it usually uses Poser 11, with units set to inches. Except when it's using Poser 6 or PP2014, or when its units are set to PNU.

*also available in ShareCG, DAZ, and HiveWire3D flavours (the DeviantArt and CGBytes flavour have been discontinued).
