Sun Target moving

[Nico1988]

Hello Evryone,
Since I've installed the last version of 3DsMax and Chaos Corona Renderer 11 I'm facing a problem regarding scenes where I use a simple setup (Sun+Sky). Everytime I close a scene and re-open it I see that the target of the sun ramain in place but the sun is moved from the initial position. I've alredy tried to lock Sun and target position/rotation/scale but didn't find the solution. Do someone have an idea of what's happening?
I attach here some screenshot.

Did you check if there's animation keys on the sun and its target, or maybe if their hierarchically linked to something else, other than target to the sun? Also check motion panel for any assigned controllers. Alternatively you could try to create new Corona sun and see if it acts normally. If all that fails, please strip away the scene from any unnecessary assets and attach it here, so someone could take a look at it.

Hello Romullus,
Yes I've already checked everythig regarding animation key frame or linked object to the sun or target but I haven't found something. I've also tried to keep only the walls and the sun and this happen averytime I close and re-open the scene.
I found this solution bout i doesn't work if I render on sleave.. Mooving a bit the sun and clicking CTR+Z the sun goes to the right position. If i render locally it works but if i send the render to another machine the sun goes in wrong position.
This happen also i new scenes made from zero.
Any other suggestions? :)
Thanks in advance

Can you attach to the message the scene with just a Corona sun in it? Assuming that the issue is still present in it.

[Nico1988]

Yes sure, here attached you can find the scene with only the sun.
I've tried also to delete the sun making a new one but the problem remain
In the screenshot you will see what happen when I save/close/re-open the file.. the target remain in place but the sun is in the wrong direction.

[romullus]

I get the same disjointed sun with its target when i open your scene, however it jumps back to its target as soon as move either the sun, or the target. Saving the scene and opening it again makes the issue re-appear. I also tried to create a new sun and it acts as expected. Attaching your scene with added new sun (Corona sun003), just to see how it behaves on your side.

I don't have any solutions to this issue, other than try to delete your 3ds Max ENU folder and see if that helps. Don't forget to make a copy, since nuking that folder will wipe out all your customization!

Thank you Romullus for you interest.
I've tried right now to merge the scene to another new file without the sun and create a new one but the problem reappear again.. Maybe I'll try to jump back to Max 23 and Corona 10 to see the result.
Thank you again

Saved the file in 2023, opened with 3dsmax 23 + Corona 9 and the problem diasappear. Maybe its a bug of Max 24

[romullus]

I'm working with Max 2024 and it doesn't happen to me. Anyway, glad to see that you've solved the issue.

I had the same problem after updating. Almost every scene created in corona 10 and re-opened in 11 appeared with the same problem, target being moved. One of the thing causing this problem, may be corona color correct map. In my case, scenes with a moving target had the same scene environment. Set up by connecting the corona sky map to the corona color correct map then plugged to single map. After disconnecting the corona color correct map and setting up coronaSky to a simple map, problem seems to be solved. Other solution was to disable the sun target. Still, using both of these solutions ale mildly frustrating so I'm looking forward to see more optimized solution.

[Nico1988]

Exactly.. this happen on scenes made with 3dsmax 23 and CR 9/10. Onestly I didn't try to unplug color correction map to the sky but I will try. Hope someone of the Chaos Staff take in consideration this topic because it's really frustrating and acually I jumped back to Max 23 + CR 9 for avoid this Bug.

[romullus]

Ok, i'm moving the topic to bug reporting board.

@brazzda, if you could attach simple scene where the bug is present that would be helpful. There is already one file attached by the OP, but having more samples can't hurt.
