Super buggy :(

wrong_1 Wrong reflection

wrong_2 WTF???

codeonwort commented 4 years ago

OK... What am I doing wrong?

For gbuffer pass, some materials output world-space normals and others output view-space normals in their pixel shaders!
Cubemap sampling direction is definitely weird. Don't know the reason yet, just did random sign flip in various places.
Specular is just... way too dominant for surfaces with low roughness.

View-space and world-space values are all correct (as I believe) but reflection is still wrong :/

What's wrong was the camera position, not view vector nor normal vector. I feel stupid...
