Hello we get the below error with a crash on IOS only sometimes (it seems to correlate with complex room scans): " Gu::ConvexMesh::checkHullPolygons: Hull seems to have opened volume or do (some) faces have reversed winding?" Below is more info. [Physics.PhysX] Gu::ConvexMesh::checkHullPolygons: Hull seems to have opened volume or do (some) faces have reversed winding?
