How to do Multilayered Cameras With 0.4

So I'm using the subcamera script for my world cameras, and the main OVRCameras for my UI cameras.

I'm getting an odd bug where the right eye sees the UI rendered for the left eye as well as the right (as if a render texture for the left eye is not getting cleared before it draws the UI for the right eye)

If I make the right eye have less depth than the left eye, the bug switches sides (so that the left eye sees double and the right eye is correct).

I'm going to try making the main cameras render nothing and adding a second set of sub cameras to render the UI, but I'd like to know if anyone else has seen something like this?


*Edit* found the solution.

It was a problem of camera depth, specifically that I was rendering pairs of cameras together:

LeftCamera1 : 0
RightCamera1: 1
LeftCamera2:2
RightCamera2: 3
etc...

When I swapped that around to render all the left eyes, then all the right eyes, stuff started working correctly:

LeftCamera1 : 0
LeftCamera2: 1
RightCamera1: 2
RightCamera2: 3

[EDIT: issue solved]
I have an issue with a two-layer camera setup as well.

Any idea how I can get this thing to work with Oculus?

I'm using forward rendering and DX11 is disabled from Unity.
I've tried nested cameras (Right/LeftEye OVRCamera gameobject with a child gameobject that has OVRSub Camera script), siphi's approach of several gameobjects with OVRSub Camera script, and several different camera depth value combinations.

Image Effects don't work still as far as I know. This issue is still not solvable until the SDK & Unity make it possible to layer multiple camera effects into a single render target.

I'm no expert but I think the depth buffer is cleared each time a new camera access it.

SDK Version 0.4.3 Beta

•Improved support for multi-layered rendering. Just instantiate multiple OVRCameraRigs, set Camera.depth and Camera.clearFlags for each eye, and use.

Woot!

Yep works pretty much like it did in 0.25 now which is great, also you can enable and disable different controllers without issue.

Hello ! New user here : ) Been following this thread and well. Are we still stuck in the we cant render image /post effects or is this solved with the new sdk. Trying to get this one working but im not sure it ever will as it is now.

Image effects should work fine with multiple layered cameras now. Unity has fixed a bug in their rendering code. You should be able to instantiate two OVRCameraRigs, set Camera.depth on their child Cameras so both eyes from rig A render before either eye on the rig B. Then you should set Camera.clearFlags = ClearFlags.Depth on both of the child Cameras under rig B. You need Unity 4.5.5f1 or newer and Oculus Unity integration and runtime 0.4.3 for this to work.

Thanks! i am currently running 4.6 might need to downgrade

Hmm, I scrapped the complicated but functional setup that I picked up from this thread and just implemented the default setup and I have a significant lag between camera layers again (far cameras rendering are a frame or two behind the near cameras). I may have jumped the gun on this, but I'm a sucker for simplicity. I probably should have left well enough alone, and I might have to revert back to the subcamera script.

Anyone else have better luck?

That's odd, the two cameras should render with no difference in latency. You might want to double-check Camera.depth. Your near rig's depth should be higher than your far rig's. Have a look at Assets/OVR/Scenes/MultiCamera.
