Using Roadrunner version 2020a update 3.

Triangulation settings are all default except "marking construction type" changed to "floating" and "Floating marking offset" changed to "0.02"

Getting below warning mutiple times after Opendrive export.

"> WARNING: Multiple triangles detected in polygon walk. Vertical gaps may be present in final triangulation."

What causes this warning? and how to resolve it?

I understand that using RoadRunner version 2020a Update 3, you are receiving the error "> WARNING: Multiple triangles detected in polygon walk. Vertical gaps may be present in final triangulation."

The warning you are seeing relates to minor geometry/triangulation issues in the scene and can be safely ignored. If you continue to have issues, you could try switching to using all default settings.

If you are experiencing crashing that accompanies the warning, that may be a separate issue.
