As = long as they're the same, anything at position 0 will not change in = size: transform.position[2]*-1 -Chris On 28/01/2012, at 5:07 PM, scott.aelist wrote: > I'm using a standard AE camera 35mm, and I want to transition from a = normal lense to an isometric style lense, but i want my subject to stay = relatively the same size in frame.
