- proper FileTransform usage

When you say your FileTransform results differ from Nuke's, is this from using a Vectorfield node, or an OCIO FileTransform node, or perhaps an OCIO Display node entirely? Also what format of LUT are you using?
(I'd also recommend using INTERP_TETRAHEDRAL where possible)

I need advice on the correct way to use a LUT file transform in an OCIO processor. My results when using a FileTransform look different than in Nuke, with whites appearing more subdued using the test LUT I have. Am I doing this right?
My normal OCIO processor looks like this:
DisplayTransformRcPtr transform = DisplayTransform::Create();
processor = config->getProcessor(transform);
However, I also allow bringing in an external LUT file, and I use it like this in lieu of the DisplayTransform:
FileTransformRcPtr fileTransform = FileTransform::Create();
GroupTransformRcPtr group = GroupTransform::Create();
processor = config->getProcessor(group);
I'm using the same display shader for both.
