Hey guys, thanks for you answers! So one would grade aces material in Nuke by only looking at his viewer rather than picking a shade from the color wheel I guess. Anyone wants to chime in, production

Thanks Matt - that code is pretty much what I already had. But the Nuke code doesn't handle a channelHot of 1,1,0,0 either. When I do this, it solos the alpha channel instead. On

Hi Paul - The Nuke OCIO Display node does that and also sets up a matrix transform for a swizzle with setChannelView() --

I'm trying to figure out how I can get just red and green to show up for example. I've tried setting channelsHot to [1, 1, 0, 0] in the MatrixTransform::View() function but that doesn't do the right

It would be really good if we could also get the OpenColorIO-Configs up to date. 11 months is a little long for a simple update to the ACES config which Hp has had in his fork since it's release.

Hi Mark, We have a number of large changes about to land in the public repository, and whilst I know it's frustrating to see the repo stagnant, by no means is the project dead. My current goal is to

Hi all, Development in the main imageworks/OpenColorIO branch seems to have stalled. The last commit is from September, 2014, and the number of issues and pull requests continues to grow. What do

If it doesn't work, email me and I might be able help out.

Thanks for the promt reply Andrew! I'm out the office at the moment but I'll give this a go as soon as I'm back at my desk. Matt.

You should be able to create a LUT from that generator that performs both operations. Have you tried these settings? Load preset - Advanced "Camera Data" Gamma - Normalized sensor linear Range -

Hello all. We are trying to adopt a more complete linear work flow in the 3D department of the vfx company that I work for. The problem that we currently have is that 3D software ( in our case Maya

Greetings Lucien. Fellow Vancouverite here. I made a simple OCIO configuration to test whether or not colour pickers are colour managed. It is only a rotation of sRGB primaries so that it is deadly

Nuke does not use the colorpicking role and it selectively uses the roles in general as there is no direct mapping for some of them.

Hi everyone, Let me start by introducing myself, I currently work at Image Engine, Vancouver and previously I was at Framestore, London. I'm looking at doing comp work with wider gamut sources and I'm

Hi, Could you add Natron (www.natron.fr) as compatible software on the corresponding page on http://opencolorio.org/CompatibleSoftware.html ? It is made compatible in a very similar way to how Nuke

Thanks for the meetup! Great discussion and I will be putting a lot of advice to good use. Den

Hi All, For those of you attending SIGGRAPH 2015 in Los Angeles, we will be hosting a "Birds of a Feather" event for users and developers of OpenColorIO to get together and discuss anything and

Ok, thanks. In the last commit of this PR (february 2015), an OCIO_USE_LLVM opt was added so I actually built this code without LLVM. -- Marie Fétiveau Color / IO / Comp Pipeline

We have been waiting for Mark to post headers for the new plugin API. The idea is to keep the OCIO core free of heavy dependencies and for things like Expression, CTL and Truelight to be supplied by
