Hi everyone.
I'm trying to read camera zoom with messiah script. To do that I set current view to camera and use GetViewZoom(_World). But it returns 0.0. Only when viewport is set to perspective this function returns 4.0. Am I doing it right at all?
Can someone give me a tip how to solve this?

Get/SetViewZoom don't work on Camera views because zoom is a motion component of the camera. Just get the zoom channel from the Camera.

Thanks, it worked. But now I have another problem. I want to export camera to 3ds max. To do that I need position, rotation and focal length. First two are no problem, but how can I calculate focal length having zoom distance? I've been experimenting with camera parameters and looks like FocalLength = (ZoomDistance/2)*ApertureHeight. Can anyone confirm if that is correct?

lechoo,

I dont have the answers to your question, but maybe I can lead you in the right direction for help.
Try the Yahoo Project Messiah Development list.
You will probably get quicker reply's there. ;)
