Light Functions not working with Orthographic Rendering - UE5.3

Hi,

I am trying to create cloud shadows using FBM noise within a Light Function.
The shadows display properly in the editor and with a perpective camera in play mode.

However when switching to an orthographic camera the effect does not work anymore.

Anybody else has encountered the same issue?
Is there support for light function with orthographic cameras?

Thank you!

Just wanted to bump this and say it does indeed seem to be an issue with the orthographic camera and the directional light.
Adding a light function to a normal spotlight or pointlight works as intended
I have submitted a bug report for ue 5.4.2 regarding this.

I just encountered this issue in Unreal Engine 5.5.1 so the bug seems to still exist. Can’t get a simple light function material to work with the Orthographic Camera and directional light, works fine with Perspective Camera.

I have started a post about it here UE 5.5 - Orthographic Camera and Light functions

This is related to the 5.5.1 engine version
