Custom Niagara Parameters are not highlited anymore when selected in the Parameters Tab

Hello [mention removed]​, you’re absolutely right.

I’ve re-tested the behavior in UE 5.5.4 (launcher and built from source at CL 40574608) and I can now reproduce the issue. Apologies for the confusion, I realized my earlier test and screenshot were from UE 5.3.

This appears to be a regression introduced in 5.5. However, I’ve also tested in UE 5.6 preview and a recent build from Main (P4 CL 42589677), and I can confirm that the issue is no longer present.

It’s safe to say this will be resolved with the official release of UE 5.6.

Let me know if this information works for you.

Best,

Francisco
