Hi
I think this is a possible bug unique to Mac, and possibly unique to specific models.
When viewing my project in-editor the directional lighting looks perfect. It is also rendering correctly when running as a simulation, and as a standalone game.
However, lighting is not rendering correctly in the packaged version. I have a directional light and a point light in my scene. Both of these are not rendering properly when packaged.
There is no shadow from the directional light where it should be, but there is a weird moving shadow on the roof of my scene. It seems to move with my player, but it is not anything attached to the player.
The point light is also rendering strangely in-editor (see the image). It seems like shadows are being rotated 90-degrees onto the wrong surfaces. Maybe this is also happening with the directional light when packaged. It could be a problem with lighiting direction/rotation in general??
The sky light and the post-processing look fine. Maybe because they don’t have a direction and they affect the scene in a uniform way??
I have tried creating a new project and migrating the level. Same problem.
I have had the same issue with several projects since using my new Mac. It is a 2020 Macbook Pro, and I am guessing that the problem is unique to specific machines.
The same projects are rendering correctly on my old 2015 Macbook Pro (with the same project settings).
I have updated to latest Xcode v12 (and I had the same problem with v11) and I am using OS Catalina. UE version is 4.25.3.
The cofusing thing is that directional lighting renders properly in editor, in simulation, and in standalone game. Only packaging has a problem.
Any help would be appreciated.
Image: This isn’t where I want the light. I’ve just moved it to make it obvious. The shadows on the walls are the shape of the desk and chairs. There is only 1 point light in the entire scene, and it is responsible for these shadows.
