    Hi,

    I think angle based culling would be a great addition to the existing CullInstances API.







    I coded this a long time ago (summer 2021 I think) in my burst + jobs version of the HDRaytracingManager, however, since I have switched to CullInstances, I would love to see the same functionality there.

    Hey, thanks. It does make sense and it's something we already had in mind as well when adding this culling API.
    We never developped because of priorities and lack of resources.
    It's not out of the question one day but I don't see it in the near future.

    Also, don't forget we do accept PR's in this public repo if you already coded it ;)

    My HDRaytracingManager was a complete replacement on the HDRP package side, while the new setup (CullInstances API) moved the RTAS management to the engine side which I can't access, it is no longer compatible.

    So I got confirmation it's still in a backlog somewhere.
    I know that doesn't help a lot given I can't give you anything besides the fact that it's still a good idea :).
