    Optimisation: How can I cull ticks for off-screen blueprints/characters? (top down)

    Hi guys n' gals,
    I am looking to find a decent way to prevent off-screen ticking, then resume it once within the camera FOV.
    I have probably around a minimum of 200 actors ticking per level and I am noticing some performance decrease as a result (to be expected), but I don't need 90% of them ticking as I have a static top down camera with a relatively narrow FOV.

    All of my NPC's/enemies, interactive objects and misc items all follow a parent child relationship, with the parent being the main "controller" of its behaviour. In theory this should make tick culling on a large scale relatively easy once I can find out the means to do so, but experimentation and research haven't yielded much progress so far.

    Any ideas or solutions any of you have had with your projects and doing this?
Working...
