How do i simulate sunlight?

I am working on a project that in volves sunlght flooding through a window and for some reason i’m not getting ay light to pass throught the window. can somone please offer a suggestion on how to fix this problem.

the material that recieves the light after it’s filtered through the window, needs to be set to ‘trashado’ ( transparent shadow ) in material buttons.

Yep, enable the “trashado” as Modron says. But remember when working with transparancy that setting low samples can screw it up. So always try rendering a frame with full samples before taking further troubleshooting. Just so you know. :slight_smile:
