Create a 3D fog
Simulate 3D volume rays.
Finding position in 3D space based on Geometry,World position pass, Deep or manual method. Reconcile 3D position to CornerPin, Transform and Roto nodes.
A nice tool to select a chunk of pixels in 3D or 2D based on their XYZ coordinates from a World Point/Point Position Pass.
the 3D masks takes any xyz / position / normals pass and outputs a mask. You have the option of different shapes and you can also rotate them. I use this one a lot for color correcting or depth effects on 3D images.
Create specular copy of the main Camera respect of a card(mirror plane) to produce mirror reflections.
create facing ratio render from a normal pass.
Rotate Normal data
Generates reflections from a mirrorball using camera normal pass or loaded geo
