Unity struggling to show even a small number of lights

    Hi,

    In my game (work in progress) at the mo, I am using ~3-5 point lights and ~3-5 spot lights at once. Unity is struggling with that. Seems a little surprising?

    Quality settings are maxed. It's built on an LWRP pipeline.

    I would prefer to avoid baking if possible, as I want shadows and stuff to reflect on the player. I wrote a script to ensure the lights were off when the player was off-screen from them, just to make sure they weren't adding to the load.

    Is there something else I should be doing?

    Thanks,

    A

    Not sure why this thread is ignored - maybe I've asked a stupid question? Either way would be good if someone could please let me know.

    "Unity is struggling" isn't exactly helpful. Do you mean it gets really slow in the editor? Or in the built game? Is it on desktop, console, mobile?
    If you are targeting mobile, having more than a single light is already pushing it a bit, especially with shadows.

    Go to graphics settings and increase Pixel Light count to more than 4.

    If you're not building for mobile then don't bother with LWRP, and even if you are, the built-in pipeline is what all other mobile games use anyway. With built-in renderer or HDRP you can used deferred rendering which is better when using more lights.
