Hi all,

I'm currently in the process of learning lighting for my Daredevil environment and started using lightmass portals. Based on a UE forum I found by Koola, these + certain post-process settings can help achieve realistic lighting.

I want to shape the portal to the same shape as my arched window here for more accurate shadows. Is there a way this can be done or can the portal only be a rectangle/square shape?

Below are images for reference.

Thanks in advance!
