DllNotFoundException
Hey All
I've been having a bunch of issues regarding Unity and Dlls.
My scene using the Oculus ran perfectly a few weeks ago, and after adding Wwise to my project I've suddenly encountered this:

I've encountered similar with Wwise also (Link: http://i.imgur.com/uzLw09n.jpg)
I've tried dragging the Dlls into the root Unity Editor folder (in C:/Program Files.... etc) but... No dice. I've also searched other previous threads and tried updating the C++ also, again no dice. The weird thing is that the Tuscany demo still works; but my game does not.
Any advice? Thanks a bunch

- cyberealityGrand ChampionCan you try re-importing the Oculus integration package into your project?
- bassman2112Honored GuestI just removed the previous plugin, and all files associated with it; but the same thing happened =/
- cyberealityGrand ChampionThe DLL belongs in the "YourProject_Data/Plugins" folder. However, it should automatically be put in here when you export. Again, have you tried re-importing the Oculus unity integration package?

Apologies, I hadn't mentioned that I did reimport the package, and that the dll was indeed in the Plugins folder. - cyberealityGrand ChampionIf this is also happening with Wwise, then it's probably something wrong with your system. Not specific to Oculus.
- saviorntProtegeThis started happening to me as well. The rift works good with my previous project, but when I created a new one to test some FBX imports, it won't work, it's as if the OVR prefab isn't working with the headtracking. Oh, and I also fall through the floor / no models are loading, and getting 40 fps with only the OVR prefab, a directional light, and this fbx model (the model is of a floor, and yes, collisions are on)
- virrorExplorerThis happend to me as well, it was al working perfectly then one day when opening the project the dll was not found. All other dlls i was using was found though.
- grodenglaiveHonored GuestThat happened to me as well - also the OVR tab had disappeared from the inspector. I assumed it was because my 4 month free trial had run out. I signed up for another 1 month trial after that (surprised it let me). This didn't automatically fix my project file, nor did re-importing the OVR package. I had to start a new project, import the OVR package and then import the scene from the project that stopped working. Pain in the ass, but it did the trick.
- grodenglaiveHonored GuestI forgot to mention, I'm not using Wwise in my project.
- cyberealityGrand ChampionHey guys, I am going to have someone look into this since it has seemed to effect more people.
Can you please list your PC specs (especially video card), operating system, and version of Unity?
Thanks,
Andres
