Min Region Size not working

See attached image. No matter how high I set Min Region Size some small areas persist. Some do disappear though, for example on the yellow bus. Bug?

Hi

It’s unfortunately a limitation that it cannot remove small regions that are adjacent to tile borders. If you want to remove all of them, you could disable tiling on the recast graph. Or, alternatively, use the RecastMeshObj component to mark your vehicles as completely unwalkable.
