Sun does not respect C4D Takes (or C4D takes doesn't like Corona Sun)

I’m having an issue with Corona Sun and C4D Takes. It happened first one or two versions ago and does still happen in the latest daily build. Here are some facts:

I have a Corona Sun object in the scene. I’m using the C4D takes system to activate or deactivate the Sun. But somehow the Take system can’t “save” the correct property for the Sun object. Here is what I do:

  • Corona Sun is disabled in the main take

  • switch to the child take and activate it (it is now saved in the take system)

  • switch back to the main take (the Sun is now deactivated again, which is correct)

  • switch back to the child object, the sun remains disabled, but it should be enabled, since it was enabled in the first step and saved

  • the same happens when I do it the other way around.

.

  • Happened with different versions of Corona and C4D. R20 and 2026, Corona 15 (maybe before, don’t remember) and daily 16 from August 20.

  • I have no clue why it does happen and when. It only appears in bigger scenes.

  • I’m not able to reproduce it.

  • It does only happen with Corona Sun object. All other object work as expected.

  • It does only sometimes appear. It happens, that in a scene one Sun does work and the others don’t.

Is any of you experiencing the same issue?

Why can I not upload the C4D or zip file here? Somehow I get an error…

Edit: I made a bug report with the C4D file

I can see that you also reported this as support ticket #511599. Let’s continue over there and share any important updates here once available.
