Does anyone know what's the exact difference between the depth of the SceneTextures alpha channel and the SceneDepth node?
What I know so far is that it's inverted (becomes darker as depth increases) and that it has a different range. Not sure for the linearity.
The interesting part is that the overall instruction count is lower if you use SceneTexture depth. It might also come handy (performance-wise) for some special operations, like blurring the scene texture and the scene depth in a single post process.
