This is used in a lot of the objects and demos so very strange. I’ll take a look at the SceneOutlineShape ASAP.
EDIT: Yes, I just spotted the mistake. It’s checking the span size for max-polygon-vertices which is wrong. The span length should be unlimited! You can track the fix for this in the following link. It’s a trivial fix so I’ve already applied that and pushed it for review.
Thanks for the report!
