    Hello everyone!

    I'm trying to do some operations with reflection probes in the shader, but I can't figure out exactly how HDRP works with it. The Standard and Universal render pipelines use unity_SpecCube variables, but I can't find anything like this in the HDRP shaders.
    So with which variable or function can I get the cubic texture of the reflection probe in HDRP?

    Hi, it is not possible to access reflection probe (neither lights) in a material with HDRP. Our lighting is decoupled from Material and we used a tile/cluster renderer (light list is build after the GBuffer pass)

    What about the _EnvCubemapTextures variable? Looks like it contains an array of reflection probe textures? Can I get some data from there? Or write them there from some part of the code?
