Re: OCIO Aces with Render AOV Group Enabled washing out Output!

Sorry to be this insistent, I'm really trying to figure all this colorspace out.

I have been doing several tests with AgX, and the problem seems to be the same as happened with ACES:
If I render PNG or PSD without AOVs it renders fine, like in Live Viewer. However, EXR is washed out even when AOVs are off.
If AOVs are on, I need to turn off color management in After or Photoshop so the color of the render, no matter which format it is, isn't washed out.

Looks like a bug to me, because I'm not sure that makes sense. But probably I'm not getting this right...

Btw, really like the AgX look, I will dig more into it, thanks :)

Washed out means that some color transform(like linear/sRGB) applied without need. You don't need to do if you save as EXR, it's without any color space conversion have for saved pixels. OCIO does it actually in render level. Just disable color display profile

Please, do! And never apologize for being inquisitive.

^ this, or in other words: double EOTF (non-linear sRGB transform, applied twice).
Users often (too) rapidly conclude that it is a bug while it is in fact, either a misunderstanding (fair enough) or clumsiness (it happens). Which will eventually happen (sometimes by inadvertence) as "color management" is mystifying (at first).
