*Steps to reproduce:*

1. Open attached project

2. Go to game view and notice the sun disk on the PBR sky and through the transparent object

3. Select visual environment and set the sky to none

4. Observe the sky disappearing

5. Enable the pathtracer

*Actual results:* We see the sun disk through the glass window

*Expected results:* I believe the transparent object make it fallback to a sky texture or something but we shouldn't see the disk I believe
