Hi, I have a really basic noob question, but after all these years I've realized that I'm not sure what I'm doing lol.
Years ago, all I was using for normal maps was the NVidia plugin and we had to flip the Y axis (check in "Invert Y"). It was somewhat common knowledge back then. And since it was looking good in the DDC and game viewer I used those settings. Nowadays, I'm using xNormal and nDo, and I don't have to set anything to have similar results. But I just noticed that their preferences are in X+Y+Z+. So, my question is, NVidia's plugin is flipping Y by default so I have to re-invert Y? I've heard that Unreal engine requires to flip Y, so if I'm using NVidia plugin I should uncheck everything and have it by default? and if I'm using nDo or xNormal should I invert Y? Thanks Martin
