(int32): [Read-Write] * Max LOD that this node is allowed to run * For example if you have LODThreadhold to be 2, it will run until LOD 2 (based on 0 index) * when the component LOD becomes 3, it will stop update/evaluate * currently transition would be issue and that has to be re-visitedmax_iterations
