Hello everyone, I'm attempting to zoom in/out an scene in their Parallel view. For this I use the SetScreenScale to increase and decrease the screen scale and it works fine. In Perspective view I change the value of z coordiante in the View Platform Transform to do the zoom effect. Change the screen scale has not effects in perspective, Why ? What is the meaning of screen scale ? Thanks in advance.
