Workflow Nodes
The Workflow nodes deal with the bread and butter functions required in compositing, but within a VR environment.
C_Blender is a utility node that doubles as a Merge node to combine all images together after manually correcting a stitch.
C_SphericalTransform is a tool to convert between different projections, both 360 and partial frame, allowing you to rotate and define the space with a variety of different controls.
C_STMap is a GPU accelerated version of the Nuke STMap node, which uses a stitch_map or ppass_map to warp another image, such as when applying lens distortion.
C_Tracker is similar to Nuke's standard Tracker, but with the addition of CameraTracker-style auto-tracking and pattern tracking in lat-long space.
