In 5.3 we would use an extra nDisplay viewport with a Projection Policy of Type “Camera” to render a direct camera view without the forced-perspective projection of "Mesh” or "Simple”.
In 5.5 and 5.7 (the only ones we’ve tested), this still works but “Freeze Viewports” now freezes those. Our inner frustum on mesh-type viewports still work, and the outer frustum freezes as expected, but these extra cameras (which we’re using on LED panels for lighting) now also freeze.
Does anyone know of a way we can only freeze the outer frustum and not these extra camera-type viewports?
