Level Design Lighting/shadow issue

[Alex Milo]

Got this weird issue when building the lighting. It dissappears if I play the map and point the flashlight at it, so must be a shadow issue. Anyone got an idea of how to fix it?

Maybe no UV map?

How would I confirm or deny this? Haven’t experienced this error before so not used to mess with UV maps.

Open the mesh in content browser and check UV1 channel

If this is a TWI mesh, then the Lightmap for it is broken and you will just need to turn off precomputed shadows for it unless you want to fix it yourself in an external program. If its a mesh you made you need to create a Lightmap UV channel for it under UV1 (UV0 diffuse, UV1 lightmap, UV2 Splatmaps).
