Where can I set the BCast Dynamic Shadow to false?

Large actor receives a pre-shadow and will cause an extreme performance hit unless
→ BCast Dynamic Shadow is set to false.

I tried to find the BCast Dynmaic Shadow.
But so far no luck.

Where can I set the BCast Dynamic Shadow to false?

Thanks a lot for any hint!

Do a search on the light without the B. B means it’s a boolean. You’ll find it under the expandable advanced section of the light.

okay, thank you so much. I guess I misunderstood. I thought this BCast Dynamic Shadow would be different from the general Dynamic Shadow.
THANK YOU SO MUCH, you made my day!

cheers :D:)
