…and so I wrote my own geo rasterizer to be able to bridge texture seams by generating a lookup UV map. Really pain in the assy stuff. But now I can generate the rain streaks without any visible texture seams at all. So that’s a significant win!
I will use this kind of rasterizer a lot.
you basically generate a adjacency uv map like this.
