Hello,

I am creating a scene with Unreal Engine models which I found in the library.

When I create a scene with cameras, the lights which are outside of the car window can not be seen behind the window in Perspective View (camera selected). I’ve unchecked the Cast Shadow box already but I cannot understand why a glass material which has opacity of 0.2 is blocking light.

I hope you can help me.
