UE4 Custom Lightmass Portal Shapes??

Amank679 · Feb 2020

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!

It can be only a rectangle.

Yeah there's no real need to have super accurate portals, since all they do is tell Lightmass where to focus more rays.
