Hello. I am using Unreal Engine and LiDAR Point Cloud.

I was testing shadow rendering, and I encountered a situation where shadows appear in some versions of Unreal Engine but not in others.

The steps I took were simply adding a point cloud to Unreal Engine and enabling “Cast Shadow.” However, in version 5.4, the shadow does not appear, while in version 5.3, the shadow was displayed correctly.

In version 5.4, the shadow appears when I change the Contact Shadow setting, but other shadows are not displayed, which is causing me trouble.

I haven’t fully investigated whether additional settings are needed in version 5.4, but if you have any advice on how to resolve this issue, I would greatly appreciate it.

Thank you.

Hey, this is because in UE 5.4 Epic set the default value of the CVar `r.Shadow.Virtual.ForceOnlyVirtualShadowMaps`to 1. Since the LiDAR plugin does not support virtual shadow maps, you won’t get shadows. Setting the CVar to 0 should give you shadows with “Cast Shadow” set on the point cloud actor.
