AgX in Corona

[piotrus3333]

Thank you Piotrus.
I like Kraken.
What's good about ACESOT that this one doesn't seem to help with is with highlights and the color shift in the hue of highlight gradients.
Good to have though.

sounds like something is not right with the setup.
screenshoot?

Here you go.
The higher I go with AgX the more pinkish hues I get.

EDIT: with Kraken it's better than with base.

you need 2 luts: A and B. B needs “logarythmic” option on. edit: both at 1.0 opacity:

Sorry! I missed that screenshot. I went straight to your post #8. I'll try this setup.

It's great. Like the guy in the video said, it gives you something to work with. Definitely needs contrast and saturation, but as a starting point is very good.

Excellent video this one:

^^Yes... more on & in-depth.

actually, the trick of the two luts, one for the color matrix (especially for controling the "above 1" color values), one for the curve is pretty interesting.

i made a few of my own for the matrix and for the 1dlut curve, maybe less scientifically correct as the one of piotrus, but the results are nice !

thanks for the tip !

unfortunately it's impossible to be really precise with luts in Corona:

- you can (probably, I have not tried) improve my matrix lut by creating one that will cover 0 - 16.something float range
- 1dlut as the second lut is the right way to go (in that case look lut can be the third one, again - probably - would be still precise enough)

edit: in general, considering ACES OT not being updated with important aces fixes from 2021, and post being done in CIE, AgX is great option for Corona users.

Hello, do you need to add OCIO configuration environment variables in the corona renderer?

Hello, do you need to add OCIO configuration environment variables in the corona renderer?

Hi, sorry, but I am not sure what exactly you mean, and also there is no need to report your own posts to moderators. :)
Can you please explain what kind of help or answer you are seeking?

[zhao liang]

Hello, I need the moderator's answer because in addition to adding lut, do I need to load the ocio environment variable of AGX when setting up AGX?

[maru]

Please note that you should only report posts if you need some help from forum moderators - for example if you posted your forum thread in a wrong forum section or if you would like to report spam.

Regarding the environment variable option - it is currently not supported. If you set Corona as your renderer and select the "OCIO - Environment Variable" you will see an error message from Corona.

no, just luts.
created with legacy gamma setup in 3dsMax 2024 in mind.

Thank you for your answers! Is it useful to add ocio Vray renderer to environment variables?

VRAY_VFB_OCIO - no.
OCIO - yes, if you are using only/mostly one ocio config.
