hello everyone, i probably use corona select maps incorrectly..
however i try to ask you for confirmation
I noticed that if I create a Corona Sky and assign it directly to Environment I get a result, if the same Corona Sky is assigned to Environment however
through a Select map the result is not always identical and I don't understand why..
For my convenience and being able to easily change the Environment seems quick as a method but I think I am doing something wrong and I would like to understand what..
thanks

You are only encountering bugs I guess. It's (almost) impossible to use them wrongly.

Generally yes. Exception is: you have cloud shadows activated in the sun. I reported that issue while testing V9 dailies, now in V13 dailies it's still there.
Good Luck

I already tried to repro it, but I can't.

Hi,
I already tried to repro it, but I can't.
Repro steps:
1. New scene with a teapot of your choice
2. Create Corona Sun with "shadowing from clouds" activated
3. Create Corona sky map with cloud amount=1
4. Create Corona sky map with cloud amount=0
5. Create Corona select map
6. Plug sky from (3) in slot 0 of the select map
7. Plug sky from (4) in slot 1 of the select map
8. Plug the select map into (any used) environment slot
9. Render and switch skies using the select map
-> when slot 1 is selected in the switch map (the sky using no clouds), you get cloud shadows from slot 0.
Good Luck

Continuing in support ticket #367681.

Hi,
We already have, specifically, clouds shadow bug fixed with select map use case, internally.
I am checking if the rest (volume effect and some others) can be fixed with this as well.
