Image effects turn the camera black.

Hey folks.

Unity 4.3.2f1. SDK Unity integration: V0.2.5 (latest).

Adding image effects is pretty random at best. Adding a color corrector to the OVRCameraController will give me a flipped image, but I can flip the Y back to solve that, however adding anything ambient occlusion on top of that will cause strange color blocking effects.

Most of the time I will now get the strange blocking with just the color corrector.

Adding anything to the cameras themselves will cause them to go black no matter what order they are placed (before the distortion for instance.)

This is all in Forward rendering.

Deferred has it's own issues and I have sadly had to not use it as the toon shader will not antialias properly.

Any ideas how I can stack these simple image effects - or if they simply will not work no matter what?

    First off, image effects should be on the cameras themselves (i.e. CameraLeft), not the camera controller. However, I do notice a black screen issue which I've filed a bug for.

    That's what I thought, but it was just a case of trying everything :)

    In any case I shall use the new SDK as soon as I can at least throw a color corrector on it.

    Thanks!

    I'm using 0.3.1. Preview. The issue seems to still persist.

    I'm trying to add an Edge Detect image effect on both cameras. Adding the effect usually blacks out the corresponding camera. If I add the effect on the left camera only, I seem to be able to get the effect partially running. Howerver, it behaves erraticly. The detected edges move correctly as the camera chanes perspective but the object fill seems to be frozen in place. Here is a screenshot of the bug:

    Additionally, I noticed that the order of the components on the camera resets every time I run the program.

    For the effect order, you will need to hit "apply" on the prefab after you move them for it to stick.

    In terms of the effects looking weird, can you try adding another "dummy" effect to the camera. For example, a tone-mapping or color-correction effect that is set low so it doesn't look noticeable. This may help.

    The new release 0.3.2 fixes this issue for me. Is this still causing you trouble?

    Same here, although it seems spotty at best. I've gotten image effects working in 0.4.1 in a fresh project - but then my current project the cameras render black. Going to try and isolate the issue if I can...

    edit: it's weird. If I put Amplify Color on a camera, it goes black. But if I apply CandelaSSR first, and then Amplify Color, they are both working..

    edit2: I wedged a bloom in between CandelaSSR & Amplify Color, it's all working in 0.4.1
    but when I tick off CandelaSSR, it goes black

    I have the same problem with 0.4.1. I try to add the default tone mapping to both cameras and the image turns completely black. I've enabled HDR on both of course, but i do not know what else can i do for fixing this :(. I'm using unity 4.3.3f1, and I've also added the Oculus player controller to an existing project.

    Edit: I'm also using Deferred Lighting. I've checked other post that say to deactivate the camera texture option in the OVRCameraController, but i cannot find that option anymore.

    We had a black screen image effect problem, but it was only on Mac.

    The discussion here led to the solution for us which was updating to Unity 4.5.3p3
