Exposure control with Stereoscopic Spherical Camera

[Atomictroy]

While starting a stereoscopic spherical workflow, I found and read the very helpful V-Ray "Guide to Virtual Reality". I'm able to successfully render an animated VR sequence (pretty cool), but need more control over the camera exposure. Normally I'd use f-stop in the Physical Camera, but understand it can't be used with the stereoscopic camera, is this right?

Is there another way to adjust exposure? It's not very practical to simply adjust lighting in this particular scene.

I'll appreciate any input or hint on a where to look for more info.

Thanks.

Hi Troy,

You should be able to adjust the camera exposure even if the stereoscopic camera is enabled. Would it be possible to attach a file with your V-Ray setup? It can be only a camera and a plane.
