Black lens on oculus rift

Hi everybody^^

We’re making a project in ue4 for oculus rift.
Everything works fine until we connect the oculus rift. When we try to play with oculus, one of the lenses works fine while the other is almost completely black, without most of the shaders and just a couple of lights (that we don’t have in the editor).
Here’s a screen of the problem:

We searched on internet but nobody else seems to have the same problem. It shouldn’t be a hardware problem because when we try the oculus in other projects it works fine.
We’re using UE 4.7.6, Oculus Rift DK2.
The pc has a GPU Titan and 24 GB of ram.

We need to fix this problems as soon as possible because we have a deadline in a week and we need to solve a whole lot of other problems^^

Thank you in advance.^^

Little update: after a couple of tests we think that the white light isn’t actually a light but an effect of the emissive of the shader. We have other emissives in the scene and they have the same problem.

Do you see the same thing when running the game without the Oculus and using command line parameter -emulatestereo ?

There have been a few stereo rendering bugs in Unreal and a few more probably still lurking somewhere :slight_smile:

Other than that, drivers up to date and all that? What OS you running?

Thanks for the reply^^

Drivers are up to date and we’re using windows 7.
As far as the -emulatestereo command we’re unale to try it because in our .exe file it doesn’t bring up the command line (probsbly because we packed everything in shipping mode?)

Does everything work fine in local debug/development builds? Have you tried cooking a Test build?

I don’t think the problem is in the package because we have the black lens even when we play in editor. We didn’t try a development build but on monday we could certainly try

We tried in development and nothing changes.
When we try the oculus in VR-Preview, after the first time (in which it keeps giving the problem) everything works fine. When we try in Standalone Mode the problem persists every time we try.

and we’re still unable to try the -emulatestereo command (our fault probably^^" we’re c.g. artists and we have almost zero programming knowledge, this is a graduation project for a cg animation major). We don’t know how to launch it. We saw in another thread that we need to open the editor via command line and we’re not even able to do that. In case a little help (something like a tutorial maybe?) would be really appreciated^^

We tried deleting al the post process volumes, the lights, the emissive materials, the skydome, the reflection spheres but nothing changes. We checked the world settings and the quality settings (that we created through execute command nodes in the persistent level blueprints following a tutorial on answerhub) and nothing seems wrong.

We have 6 levels and only in one of them (with the same settings of the others) the lenses work fine (almost, but fine enough for us). The settings are the same.
We have 1 day untill the final deadline and we’re drowning…^^"

I think I had this problem when I tried to put a Post Process chain onto a camera… use volumes… maybe?
