Hello,
Thank you for providing detailed information about your issues.
1. The magenta tint in the clouds is likely related to the turbidity value. You can try lowering the turbidity to decrease the amount of magenta in both the sky and clouds. Adjusting this parameter should help.
2. Regarding the slight shift in clouds' pink tint when using Corona Sky with Corona Color Correct, I'm not able to reproduce this issue on my end. In my testing, using Corona Sky with or without Corona Color Correct maintains consistent results. Please ensure that all settings are applied correctly, and if the issue persists, feel free to provide additional details or share specific settings for further investigation.
3. As for the shift in colors when turning on clouds and the overall darkening of the sky, I'll get back to you with more information from the devs.
4. Regarding the banding issue, it appears to be not related to Corona but possibly a 3ds Max-related issue. Try using the native 3ds Max sun and sky and check if the banding is still present. I'm also looking into this, as I've observed similar banding with the native sun and sky in 3ds Max.
If you have any more details or updates, feel free to share them
