Ok im using poser pro 2012. I have tried two different scenes and keep having the same problem. I have highlighted the problem in the attachments in yellow. For some reason when i render the wall/window bloons and expands for an odd reason. This only shows up when i render and not in the preview while im designing the scene.  Any clue? I have tried to deleate key frames but that didnt work. Also have tried to created a whole new scene and still it happens.   Could it be from one of the two characters that i import into the scenes?

 

Thanks for any help as this is driving me nutz the last two days =-(
