Custom Primitive Data Not Working in Unreal 5.4

[rohangulig]

In Unreal 5.3 after turning on Custom Primitive Data in Parameters it was working fine but in Unreal 5.4 using same steps Custom Primitive data stopped working. Is this a bug? or in 5.4 it needs some extra steps ?

Looks to be working, my 2 steps just in case it helps you notice something. Try testing runtime too just in case.
