I've been banging my head against the wall on this one. We recently released a game on SteamVR and are currently trying to port to Oculus. Everything works great, however when I try to upload to the Oculus store, it gives me errors saying my package contains a number of DLLs that Oculus doesn't like. The thing is, I have disabled just about ever plugin in my project and Unreal still builds a package with these DLL files. If I manually delete them, the app won't run either (it just spits out an Unreal crash log). The DLLs include Physx, Ogg, Vorbis, and a couple others.
I would absolutely love to get this solved so I can publish to Oculus!
