    You can avoid running the "m_MissingSHQueries" code by ensuring that your entities already have the corresponding light probe components when initially loaded, which saves the light probe system from having to create them.

    We will try to optimize the Hybrid Renderer ID allocation in a future version.

    Also, make sure you have leak tracking completely disabled when profiling this, as it significantly increases allocation costs.
