Tetra-DCTLOFX

The Tetra transformation, as described by Steve Yedlin ASC, originally implemented by for Nuke by calvinsilly, ported to Fusion by EmberLightVFX, and presented here as a DCTL for the ResolveFX DCTL plug-in.

Installation:

  1. Find Your LUT folder by opening File>Project Settings. Select Color Management, then under Lookup Tables, click Open LUT Folder.
  2. Put Tetra.dctl in there somewhere.
  3. Restart Resolve.

Usage:

  1. Apply DCTL OFX from ResolveFX Color category to desired node.
  2. Select the Tetra.dctl file from DCTL List

Note: Control parameters are "normalized" so they are zero at unity. But, for the algorithm, values must correspond to their actual position on the cube. eg: the Red-Red value must be 1.0 at unity, so 1.0 is added to the entered value.
