Hi everyone,

I’m working in ACES using the default OCIO config in Houdini, and noticed something odd. In COPs when I use a Mono To RGB, with one of the default color ramp presets, the colors look too saturated or blown out.

If I run it through an OCIO Transform node (from Linear Rec.709 sRGB → ACEScg), the colors look correct again (to my eyes).See screenshot.

I thought Houdini handled these color conversions automatically — am I missing something? What's the correct workflow/setup here?


Update: I can leave the OCIO Transform node "To Space" on scene_linear with the same result.
