Description
I wrote a radial blur effect. When I used it with the Bloom effect, I changed the degree of radial blur through the leva control panel and found that the Bloom effect did not work, but if i give a Bloom Effect an unique key it's work, I don't understand what caused this.
i make a demo to show that
here is link: demo

Research direction
Start with the linked CodeSandbox demo and reproduce the interaction between the custom radial blur effect, Bloom, and the leva control panel. Compare behavior when the Bloom effect has no unique key with behavior when it does, then trace the relevant component updates and effect lifecycle. Done means changing the radial blur degree leaves Bloom functioning without requiring a forced unique key.
