This is fixed in the next release.An issue I found with the latest V4 build. Changing the cameras White Point does not update in IPR.
edit: same for sky color, sunset color, ground color, stereo left filter and right filter.
Can you explain the use of this pls? It is not a trivial change, as things like the render buffer size would need to change each frame during an animation, so if there is another way to achieve what you are trying to do, that would be good.Keyable camera resolution would be nice too
