Building light causing weird shadows.

Development Rendering

I have point light with a long Source Length and a cube (from Unreal Content) on the wall.

This is what looks like before I build the light.

As you can see, the shadow is in the correct place. (shadow to the right/top of the cube).

After I build the light this happens.

The shadow goes to the bottom like I have a light in the middle of the wall…

This didn’t happen on 4.18.

Here are the details of the pointlight.

EDIT:
I’m not using any custom mesh or texture, just a simple Cube from the editor and white base colour (For the walls and for the cube to create shadows).

What can I do?

Thank you for the help.

Thank you

I think I found the same problem already on issue page.

UE-56344

Hope there are some developments for it. I also submitted a bug report.

If anyone knows any alternatives to do “piped lights” I would be grateful.
