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.

For my convenience and being able to easily change the Environment seems quick as a method

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

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

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.
