I’ve downloaded hundreds of surfaces from this link https://quixel.com/megascans/home?category=surface , and now I’m wondering if these are made for DirectX or OpenGL. If they’re for OpenGL, I’ll need to invert them all?
Hello, When you’re downloading textures and surfaces from a site like Quixel Megascans, they typically provide textures that are supposed to be compatible with both DirectX and OpenGL pipelines. However, the key thing to watch for is whether the texture maps (such as normal maps) need to be inverted based on the coordinate system you’re using. If the concern is about normal maps, then yes, if you’re switching between DirectX and OpenGL, you’ll need to invert the green channel of the normal maps.
How should I know which is which to invert ?
