I am working on a VR scene that is being implemented as a stereo cubemap. I am running into issues using post effects. The scene is an arena and requires bright lights with strong light flares and bloom. Unfortunately the post effects breaks the cube map by bleeding the lens flares and bloom across the tiles, and in some cases just cutting them off entirely at certain seams. I tried adding the post to the camera, and also the render setting but this seemed to have no affect on the outcome.
I can't upload the scene or show a screenshot for NDA reasons, but I might put together a quick test to upload later today to demonstrate the issue.
