This is a series of mesh blocks joined together into a wall. Any ideas what would do this? I’ve tried merging vertices, but it only helped a little.
Maybe there is a very small position difference in vertices of the mesh that connects to this edge (remember, a normal seam means there is 2 edges, so 4 vertices), leading to some floating point difference, and some pixels end up lighting “through” the mesh. Check in your DCC to merge the vertices while keeping the normal seam.
Thank you. I merged them but it only made it slightly better. I’m guessing I need to merge harder
