You may find that turning up Style > Curve Steps
helps but if the problem persists you can make a few changes to the style so that each row is calculated independently. To do this:
- Change the vertex on either side of the bend to a Bezier - Corner. This is to force adaptive mode to start and stop segments at these points and keep the paving on straight sections aligned.
- Open the Style Editor and add a new empty
segment to the Inner Corner
inputs of both Generators.
- Change both Generator's Properties > Geometry > Y-Mode
. You can read more about this mode here
You will now have improved corners because each row is calculated separately to try to maintain the paving slabs original size on the front edge
I hope that helps but please let me know if you have any further questions.
