Hello,
I'm having trouble getting ACES/OCIO to work properly in Houdini 20 when rending with Arnold. I have followed the workflow outlined in the Autodesk documentation [help.autodesk.com] and some of the options available do not align with what I'm seeing in Houdini and when compositing in After Effects.
First, I've gone ahead and pointed by OCIO package to reference the ocio.config that ships with Arnold.
Following along with the ACES workflow documentation, I'm attempting to change the color space settings in the Solaris Render Product Node and the Render Settings Node but oddly enough "ACES" is not an available option for the "Output color family" in the Render Product Node or the "Rendering Color Family" in the Render Settings Node. Instead, I have the option of "Scene-linear" or "Utility." Selecting "Scene-linear" allows me to choose "ACEScg" in the adjacent drop-down on both nodes.
Furthermore, in the Solaris render view, I have different options in the OCIO display and view options than are shown in the ACES workflow documentation.
Upon rendering, I have those same options in Mplay. Then, when I bring the EXR into After effects for rendering, the colors are over-saturated compared to the soalris render view and the Mplay view. The color settings in After effects are:
Color Engine: OCIO
OCIO Configuration: Aces 1.3 CG v1.0
Bit Depth: 32 bits per channel (float)
Working color space: scene_linear:ACEScg
Display color space: sRGB - Display/ACES 1.0 - SDR Video
Does anyone know why I'm not seeing the color spaces in the Render Product and Render Settings nodes? Is the saturation shift in After Effects due to a OCIO setting mismatch?
Thanks!
Any help would be greatly appreciated.
