Weird Light Bake Error
Hey all,

I’m getting these weird squares when I bake my lights. This is only on certain bits of kit imported with Datasmith.

I’ve checked and remade UV maps etc. but nothing looks to get rid of them. Any help would be appreciated

Using UE5.

Delete all UV channels off the mesh other than one.

Use the UV tools to unwrap a brand new UV on your channel. Create a new channel, then copy the UV into it using the UV tools still.

This fixes the problem
