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. -sean On Mon, Jul 2, 2012 at 3:58 PM, <[email protected]> wrote: > 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 > > 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. > > Andrew > > Date: Fri, 29 Jun 2012 14:01:21 -0700 > From: Sean Looper<[email protected]> > Subject: Re: [Nuke-users] 6.3v8 OCIO display lut > To: Nuke user > discussion<nuke-users@support.**thefoundry.co.uk<[email protected]> > > > Message-ID: > <CA+DGjnAx09Z0bLpa2xOgBQR_**ofDbkfw0ehWp2gg1h9z6dvp3YA@** > mail.gmail.com<ca%2bdgjnax09z0blpa2xogbqr_ofdbkfw0ehwp2gg1h9z6dvp...@mail.gmail.com> > > > Content-Type: text/plain; charset="windows-1252" > > Hey Andrew, > > Can you clarify a bit?
