    Hi! I was just messing around with the HD pipeline with a lot of lights and I found out that there seems to be a limit of 24 lights per tile. It's not that I need so many lights, I was stressing Unity a little bit. But if that limit is exceeded, graphics mess up quite a bit:

    Rendering by default, a bit of a mess:

    Disabling Tile and Cluster, looks as intended but, of course, with much less performance:

    Debug view where I noticed the 24 light limit:

    I guess there's a reason for the limit, but in case you overpass that limit, are the graphic glitches intended or is it something that it will be improved?

    Any idea how to turn off tile/cluster in the latest version of HDRP 7.1.7 and Unity 2019.3.0f3? I'm using HDRP for pre-visualization where I need to support 100+ realtime overlapping spot lights. I can't find the option to turn off tile and cluster like you did.
