Hi!
I need to know which stereo channel is being rendered on my VideoPost plugin.
I know I can use StereoGetCameraCount() and StereoGetCameraInfo() to iterate the stereo cameras, but I need to pass the actual channel being rendered to StereoGetCameraInfo() and I can't find where this information is.

Hello,
I'm afraid the the id of the currently rendered stereo channel is not handed over to video post plugins.
Best wishes,
Sebastian

So I had to reproduce this from RenderData....

mStChannelOrder[1] = -1;
mStChannelSequential = -1;
mStCurrentChannel = -1;
