Thanks for the responses everyone.
I'm attempting to reach out to some of the people who may have a connection to or interest in the project's stewardship, and will be asking them to weigh in on this

Re: State of OCIO development re: CPU/GPU mismatches
Hi,
I personally got very busy over the last year and I have been waiting to see Marks suggested changes to the core, so haven’t been involved as much as I would have liked.

Re: State of OCIO development re: CPU/GPU mismatches
Serious question, why not just publicly do a fork, and maintain it in the short term until the stewardship side of the official repository becomes clearer? At that point, the fork can be merged and

Re: State of OCIO development re: CPU/GPU mismatches
This issue not just tetrahedral interpolation, it is the fact that the existing OCIO OpenGL GPU path folds all LUTs into a single 3D LUT, and this is not sufficient for many transformations

Without tetrahedral interpolation you can get better results by creating 65x cubes instead of the default of 32x that the example OCIO configs use (very easy to create with Hp's python script included

Re: ImageBufAlgo make_texture colorspace change
I didn't check for ok in the code snippet I provided, but ok is True, and colorBuf.geterror() returns an empty string.

There is, you just weren't checking it:
import OpenImageIO
srcBuf = ImageBuf(src_path)
colorBuf = ImageBuf()
ok = OpenImageIO.ImageBufAlgo.colorconvert(colorBuf, srcBuf, 'sRGB', 'linear')
if not ok :

Re: ImageBufAlgo make_texture colorspace change
In OIIO 1.6, if OCIO is disabled (support not compiled at build time, or no OCIO configuration file is found at runtime), all it knows how to do is convert between sRGB or Rec709 and linear.

Phrases like "looks lighter in Nuke" always make me suspicious, there are too many ways things can go wrong.
Let's start from first principles.

Re: ImageBufAlgo make_texture colorspace change
It depends on the colorspaces defined in your config.ocio file set by your $OCIO environment variable. Which profile are you using from the examples or did you roll your own?
