| Changeset | Fix RGTC normal maps showing as black in lighting preview mode Although we were correctly loading RGTC normal maps into the appropriate destination format, there was no code in the shader to actually handle the missing Z value, resulting in RGTC normal maps showing as entirely black. The Z value is now recovered for all normal maps (because it's much easier than having to implement format-specific shader behaviour, and should be fairly quick), using a simple application of Pythagoras. I can't prove that this is 100% mathematically correct but it seems to give realistic results, and is a lot better than black. |
