Title: Corona Color Picker issue
Post by: Tom on 2025-05-28, 00:58:43

Hi,

I'm creating a new CoronaPhysicalMtl: I put a CoronaColor map in the diffuse slot, and I enter 0,0,16 as HSV values, I click OK.
Now, when I click on the color I just setup, it's not 0,0,16 anymore but 0,0,21.

What's happening?

It's a known issue with colour picker. Unfortunately there's not much Corona team can do about that, because it's being handled by 3ds Max. https://forum.corona-renderer.com/index.php?topic=14123.0

That's too bad. Anyway, thanks romullus.

Strangely, it seems to be working fine here. The value of 16 is kept. I am using Max 2025 and tried it with both the gamma and OCIO workflows.

I'm still on Max 2023

Yep, I can reproduce it in Max 2023. So we have proof that it is a Max issue.

Thanks. Another good reason to update to Max 2025 (or 2026).
