[COLOR=#000000][FONT=verdana]Hey there,[/FONT][/COLOR]
[COLOR=#000000][FONT=verdana]I am doing project in Flash and I have two swfs. One is loading another one. The one that is being loaded utilizes 3D tween, i.e. 3D perspective. Swfs have different sizes of stage - 700x500 and 1000x600px. [/FONT][/COLOR]

The problem that I have is following: when swf is loaded, 2D objects are okay. However 3D tweened objects are shifted. I was not able to come with proper solution, nor able to find some. Any help will be appreciated. Thank you in advance.[/FONT][/COLOR]
