So using the OCIODisplay now with the viewerProcess set to none does
give me the same result as using selections in the viewerProcess as it
should and yes the transforms are applied to all layers and channels
except the alpha.
This is a desired result you say? Why would you want your alpha not
represented the same as everything else?

The OCIO Viewer LUTs are just OCIODisplay nodes. Try inserting an
OCIODisplay node in your graph and viewing from there with your Viewer
LUT set to "None". Pick an obvious transform from the "view transform"
knob and cycle the "layer" knob through your various layers. You
*should* see the transform applied to whichever layer you select. What
you shouldn't see is the transform being applied to the alpha channels.
Let us know if you see anything different than the above.

Hey Sean,
I'm using the "rec709 (default)" from the viewer lut pulldown
though srgb has the same issue and I dont have any other view luts
currently installed. We have a custom OCIO config originating from
opencolorio.org <http://opencolorio.org>
A quick and clear test is to make an RGBA ramp and compare the RGB
and the A through different viewer luts and none.
If no one else is seeing it perhaps its to do with our OCIO setup.

Hey Andrew,
Can you clarify a bit? In 6.3v8, the shipped LUTs seem to apply
correctly
to non-rgba channels, but not to the alpha. This is the desired
behavior.
At one point there was a bug in OCIO that caused the LUTs to only
apply to
RGBA, but that fix seems to be picked up in Nuke 6.3v8. Which LUT
are you
selecting in the Viewer LUT pulldown? Are you using a custom OCIO
config or
the one that ships with Nuke?

It appears that the forced OCIO display lut in 6.3v8 is only
applying to
the RGB channels and not the alpha or other layers.
My "layer" option in the OCIOCDisplay panel is set to all.
Though changing
this to other options doest not have any affect.
Anyone else experiencing this?
