Hello. I've making procedural trigger generation and get huge spikes of "Mesh.Bake PhysX CollisionData", which takes up to 85% of frame time. All objects in heararhy has scale (1; 1; 1) and not marked as static. Here is my code Code (CSharp): _mesh.Clear(); // generating verts/tris arrays _mesh.vertices = _verts; _mesh.triangles = _tris; _mesh.Optimize(); _meshCollider.sharedMesh = null; _meshCollider.sharedMesh = _mesh; If I comment line Code (CSharp): _meshCollider.sharedMesh = null; spikes go away, but MeshCollider is not updating. Does anyone know possible solution?
