This screen is not available if you have selected a ray tracing option. We suggest you definitely use defaults at first on this screen. When you look at an image with both eyes, each eye sees the image in slightly different perspective because they see it from different places. The first selection you must make is ocular separation, the distance the between the viewers eyes. This tends to move the image forward and back to set where it floats.
More positive values move the image towards the viewer.
The value of this parameter needs to be set in conjunction with the setting of ocular separation and the perspective distance. It directly adjusts the overall separation of the two stereo images. If there is too much in the field of either eye that the other doesn't see, the stereo effect can be ruined. Red and Blue brightness factor. In general you should not have to adjust this.
