I'm working on a series of street textures that can be mixed and matched to blend seamless transitions for different street needs. I've got the texture itself blending well (mostly), but when I render it in-game, I can see the seam. And it doesn't appear to be the texture seam, but rather the seam between the brushes. See the attached photo.
Now, I've caulked all the faces of the brushes except the top faces. Is this a lighting issue between brushes and is there a workaround? Are vertices welded in this game, ie - do I need to match up all the vertices of adjoining brushes for seamless transitions?
Thanks.
