@ClockworkOcean hi,I can’t find wav files.they are all uassets.
@Hidrem i just checked. They’re in the drive folder,just don’t show up in editor content.
I guess I must accept that I must upgrade the project if I want to use new assets…
a bit unfair there was almost no sound packs before 5.4 released. 
(joking…still appreciate epic releasing free sounds)
