ocio Aces 1.0 config
G C <gcdi...@...>
Dear OCIO I am new to this and i am struggling to get my self around to find config for After Effects and FUSION using the `Ocio plugin need config where can i download the complete set or configurations smilier to the Nuke ocio integration IIF aces module and the rest How do i build my own config to for example cover an srgb to Aces cg to make clean transforms from sRGB to ACEs cg thank you in advance for helping me out and looking into this Best wishes Gene |

Re: OpenColorIO stewardship
Andy Jones <andy....@...>
Thanks for the update, guys. Much appreciated, as well as all of the ongoing efforts with both ACES and OCIO! If it seems like it would make sense in the long term to distribute ACES configs separately from the OCIO examples, I wouldn't have any problem with that. I can see where it might make it easier to juggle ACES updates and OCIO library updates. But it does seem like our best bet for getting ACES 1.0 into this year's releases might be to avoid rocking the boat too much and stick with the plan you guys outlined. |

Re: proper FileTransform usage
Mark Boorer <mark...@...>
Hi Paul, 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) Cheers, Mark On Tue, Mar 8, 2016 at 5:52 PM, Paul Miller <pa...@...> wrote: I need advice on the correct way to use a LUT file transform in an OCIO processor.

Re: OpenColorIO stewardship
Mark Boorer <mark...@...>
Hi All, Apologies Mark, I missed your previous request for an update, it's been a bit busier this year than I expected! Andy, et al; As Haarm-Pieter put it, I am currently awaiting his final changes before I can merge his ACES 1.0.1 config into the repo. At the moment, the OpenColorIO-Configs repository is not versioned in lock step with the library, so I see no reason why this cannot go out immediately. Initially I'd had some reservations about the sheer size of the commits, and that the addition of other, non OpenColorIO related data would have an adverse effect on the usability / maintainability of the repository, but people seem keen to use this repo as a central ACES reference implementation, rather than just a place for OCIO configs, so I plan on putting it through in one go.

Re: OpenColorIO stewardship
Haarm-Pieter Duiker <li...@...>
Hey Andy, Here's an update from my side on the issue. After a bit of delay, Mark and the OCIO leadership have agreed to accept the pull request to integrate the ACES 1.0.1 config into the main OCIO configs repo. They have asked me to combine the commit history into a single commit before doing so, so the commit history for the general repo doesn't suddenly have a huge list of commits that won't mean much to most people. It's on my to do list. I'm also on a project that is barreling head-long towards a deadline this week, so that's taking precedence right now. I'm hoping to have the commits squashed this weekend so the pull request can be accepted. Mark, correct me if that's not in line with your understanding.

Re: OpenColorIO stewardship
Andy Jones <andy....@...>
Bumping this, specifically WRT ACES 1.0 in the configs. It would be great to get some kind of (hopefully short) timeline on that. The configs in Nuke seem to be some ancient checkout of the examples, and we'd like to pressure them to bring them up to date for their next release. We'd really like to see ACES 1.0 included in that update. It seems like there's a chance Nuke might end up pulling from HP's github if the update doesn't happen soon, but I would imagine it's in everyone's best interest to keep everything pointed at the original repo. If there's a big refactor of the configs going on for the major release mentioned above, perhaps it's worth making a branch and merging HP's ACES 1.0 config into master until that's ready? Even if the configs are likely to need to change with the updates, it seems like places may need a legacy ACES 1.0 config for a while, until the future library makes its way into the apps. |

proper FileTransform usage
Paul Miller <pa...@...>
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(); transform->setInputColorSpaceName(colorSpaceName); transform->setDisplay(displayName); transform->setView(lookName); transform->setLinearCC(gainTransform); transform->setChannelView(swizzle); transform->setDisplayCC(exposureTransform); 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(); fileTransform->setSrc(path); fileTransform->setInterpolation(OCIO::INTERP_LINEAR); GroupTransformRcPtr group = GroupTransform::Create(); group->push_back(gainTransform); group->push_back(fileTransform); group->push_back(exposureTransform); processor = config->getProcessor(group); I'm using the same display shader for both. |

Re: Compatible software list
simon smith <si.c....@...>
Could you also add HDR Light Studio v5.0+ (www.lightmap.co.uk) as compatible software too please. We ship the OCIO configs with the main application to allow users to convert source image data into linear color space, to generated final content in the supported output color space, and also the internal views can be mapped via the native support for OpenColorIO on the appropriate display toolbars.

Re: Creating mipmapped textures with OpenImageIO
Larry Gritz <l...@...>
There is an oiio-dev group: http://lists.openimageio.org/listinfo.cgi/oiio-dev-openimageio.org
The oiiotool command line you use is writing a tiled file, but there's more to a MIP-map. When you use maketx, it's creating a multi-resolution (MIP-map levels) as well as embedding some other assorted things in the metadata that help at render time. Somewhere on my list is to add a feature to oiiotool that would cause it to do exactly the same thing that maketx does. But at present, you're expected to use maketx for that final MIPmap creation step.

Creating mipmapped textures with OpenImageIO
John Coldrick <john.c...@...>
Profuse apologies if this is an inappropriate place to ask about OIIO, but I couldn't find a group for it specifically... We've been starting to use oiiotool to prep texture maps for 3D, and recently I've been getting incorrect behaviour wrt mipmapping. We were running this on Windows and I thought perhaps it might have been an obscure bug that slipped between the cracks since most folks are probably using it on Linux, but I recently compiled oiio on centos and got the same results. If I have an exr file, already linearized, that I wish to mipmap I run: $ oiiotool ./mymap.exr -tile 64 64 -d half -o ./mymipmap.exr and when I run iinfo on this I get mymipmap.exr : 2048 x 2048, 4 channel, half openexr if I run: $ maketx ./mymap.exr -tile 64 64 -d half -o ./mymipmap.exr iinfo provides: mymipmap.exr : 2048 x 2048, 4 channel, half openexr (+mipmap) I've verified by testing with render packages that indeed oiiotool is not creating a mipmap and maketx is. I've tested this with OpenImageIO 1.5.16, 1.5.22 and 1.7.1dev - same results. Am I doing something fundamentally wrong? Many thanks for your thoughts... J.C. |

Re: color picking role, used in Nuke?

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 experience of comping in Aces/AcesCG? Cheers Le lundi 9 novembre 2015 12:47:45 UTC-8, Troy James Sobotka a écrit :

Re: disabling specific channels during view
Paul Miller <pa...@...>
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.

Re: disabling specific channels during view
Matt Plec <mp...@...>
Hi Paul - The Nuke OCIO Display node does that and also sets up a matrix transform for a swizzle with setChannelView() -- https://github.com/imageworks/OpenColorIO/blob/master/src/nuke/OCIODisplay/OCIODisplay.cpp#L337 One thing to watch out for: If I'm remembering right, this is applied before the view colorspace conversion in the display transform, so if there's crosstalk in that then you can still end up with non-zero values in channels you had zeroed out. On Mon, Dec 28, 2015 at 9:05 AM, Paul Miller <pa...@...> wrote: 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 thing. I've also tried setting lumcoeff[2] = 0 but that doesn't have any effect. |

Re: OpenColorIO stewardship
Deke Kincaid <dekek...@...>
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. Silly as it sounds, things like this actually prevent some software vendors from including the ACES 1.0 config with the official software distribution as it's not in the official release but a fork. From the user POV this causes many people to use old & outdated configs and then they are confused about why it doesn't work right. |

Re: OpenColorIO stewardship
Mark Boorer <mark...@...>
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. In addition, there is also a large amount of organisation happening behind-the-scenes to do with our official ACES implementation on the config side of things. I am working towards having this ready for feedback by the new year, and once this is done we will hopefully see a lot more activity in the open again.

OpenColorIO stewardship
Mark Visser <mvi...@...>
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 folks think about creating an OpenColorIO github organization and centralizing development there? I know there are several active forks at other studios, but looking at the official repo and web site, the project would appear to be dead. I don't imagine downstream maintainers will pull from anywhere but the official repo, so any fixes and features made in other forks won't show up in Nuke/Maya/RV/etc. best, Mark |
