I am working on a road generator that uses a curve to create a path and a spline parameter to generate UV.


However, I have a problem with handling intersections. There appears noticeable artifacts. The only solution I could find was using a boolean to make a mask and mix another material, but this did not look good and affected the performance heavily.


Is there a way to make the UV islands overlap each other instead? Or is there a method to generate a mask on intersections?

Solved by storing UV attribute right after "Geometry Generation"
