    Hello,
    Does anybody know any method tho increase the resolution of reflection probes in HDRP?
    I've seen a thread around here where somebody said that the option will be available in the 2019.x versions of unity, but so far...nothing changed.

    Is there any other way? or it should remain stuck at 128?

    Cheers,

    Hi, in the HDRP asset under the Lighting section, you have a Reflection Cubemap field to change the resolution of the probes: upload_2019-7-17_15-7-47.png

    Does anybody knows how to to increase Reflection Cubemap Size in HDRP without getting error like "This configuration will lead to more than 2 GB reserved for this cache at runtime!"

    How can I change the reserved size?

    Why are the resolution settings for reflection probes global in HDRP? I usually have different settings per probe depending on use case.

    Also, the probe gets broken (completely green) when changing resolution.. Unexpected behaviour. Texture shows correctly in the inspector, but reflections in the scene are green.

    Because they are packed into texture arrays. And texture arrays require all its items to have the same resolution.

    Hi,

    >Does anybody knows how to to increase Reflection Cubemap Size in HDRP without getting error like "This >configuration will lead to more than 2 GB reserved for this cache at runtime!"

    If you get this message it mean that you are allocating too much memory (that the binary of unity can't handle currently).
    So you need to reduce the number of reflection probe you have in the array or the resolution.

    >Why are the resolution settings for reflection probes global in HDRP?
    It is because of the tile/cluster architecture of HDRP and also for performance reasons (using Atlas is possible but can waste more memory and ALU).

    >Also, the probe gets broken (completely green) when changing resolution.
    Be sure to have latest version of HDRP for your current binary.
