Title: CoronaColor srgb values changing between file saves
Post by: Jpjapers on 2024-09-13, 11:48:11
Ive noticed recently whilst using the OCIO colour management that if i set a corona color node to a specific  sRGB colour, when i save and reopen the file they have all changed rather significantly.

For instance i have a brand colour 0,61,165 and on file open it had changed to 54,62,156.
0,0,255 has changed to 64,36,239

This isnt a one time occurrence. I thought perhaps i had screwed up somewhere but its happened to every coronaColor node. Ive switched to using pngs because i can rely on them.

Max 2024, Corona 12.

Which color selector are you using? Default 3ds Max color picker or Corona improved Color picker?

Interesting.

I was not able to reproduce this issue. Is it possible for you to help me repro this?

Here is what I did so far,

Store some color value in Corona color map, plugged it to some material, applied to some object. Saved the file. Re-opened the file. Everything remained same.

I was using 3ds Max 2025 with default ocio settings.

Im using max 2024 with default OCIO settings too.
When im at the end of this project i will switch back to using srgb values and see if i can reproduce. If i can, i will upload the file. Currently against the clock though!
