Hi everybody, I’m pretty much new to Unreal and I’m getting this strange error.
Everything was working fine but as I rebuilt the lighting, these strange shadows appeared.
I tried to increase lightmap resolution but nothing happens (UV are not overlapping).
What can it be?
Thank you for your support!
Make sure you have a light mass importance volume in the scene.
Hi ZacD, thank you for your answer!
I added a light mass importance volume in the scene, re-built the scene but no improvements in shadows 
What else can it be?
Your lightmap resolution is too low for the ground.
I increased the res to 1024!
Now is working good!
Thank you guys
