Hey everyone, hope you’re all enjoying Unreal Engine 5. I’ve turned off lumen in my UE5 project and for some reason when I set the sky light to movable I get some dark lines on my meshes.
These are my rendering settings in the project settings.
This doesn’t seem to be happening on UE4 just UE5. If anyone can help it would be appreciated, thanks.
I forget what it’s called, but this is caused by the skylight. The skylight projects black on the bottom of meshes by default, so you need to change the settings of the skylight.
Also, your sun direction looks to be exactly rectilinear with the grid. This is never good, because accuracy will cause problems. Try moving the sun a few degrees sideways one way or the other, for more deterministic lighting.
Are these cubes directly from UE5’s toolbox, or are these imported via 3d modeling software?
I found a fix after messing with the sky light. It seems that turning off shadows in the sky light fixes this issue. The shadows are still there from the directional light but less darker and look more like my unreal engine 4 projects now.
Try to toggle the Engine Scalability Settings
Try to rebuild lightning
-select directional light and change it to movable
-add a skylight to get rid of those black shadows
Hope this fixes your issue
