Hey there,
I'm wondering if Houdini19+ supports older versions of ocio config ? aces1.1 or aces1.2
I've been testing with a 1.1 aces config and I'm not getting the result I'm expecting . Also visually LUT looks different comparing to houdini18

If you have a very recent version of 19, the ocio pipeline has been enhanced to support ocio 2.0 profiles correctly. It's possible it fixed some long standing issues with OCIO view correction that would make it appear differently than 18.

What difference do you see?
