This is not a duplicate of questions asking about world scale.
This is a direct question regarding the IPD itself. I’m not talking about the physical IPD which is adjusted by the knob on the side of the Vive. I’m asking about the virtual camera distance and toe in. Not the height. How do we change the distance in unreal units between the two virtual cameras?
Our goal is to artificially induce lilliputianism and gigantism in our viewer without changing their height or counter scaling their height as the world scale changes.
