I have a scene that has a lot of reflection probes so I am trying to increase the ‘maximum cube reflection probes on scene’ in my hdrp asset, but the value keeps getting clamped to 128. Is 128 a max value of ‘maximum cube reflection probes on scene’?

It does seem to be a hard limit.

It’s said that it’s limited for performance reasons.
