The bloom effect in VRChat appears to be restricted or hard-locked following a recent update. There has been no official announcement, changelog entry, or report in the beta updates regarding this change. As a result, all VRChat worlds seem to be affected, with bloom sliders no longer functioning as expected across every world. This issue has caught creators and players off guard due to the lack of prior notification.

In the pictures below you see the Unity Editor Version and the VRChat Version. The VRChat Version is Hardlocked at "1.0"

This Bug affects all Worlds on the PC Version.
