Hey,
I get a seam when baking lightmaps for adjacent terrains. I don’t think it’s mipmap or filter issue. When I line both lightmaps next to eachother the seam is still there so it seems to occur when generating them.
I use builtin terrain and it looks almost as if I havn’t turned on SetNeighbours(). I tried running that function with RunInEditor which works as expected without lightmaps. This probably doesn’t make any difference to beast, but the issue looks similiar as if edge normals are generated wrong.
I read this 83813-Serious-Lightmapping-Issue-with-Seams thread and experimented with edge dilation setting without result as well.
Anybody got any advice?
