Christoph:It seems like I have to jack around with the focus forever to get it right. Too bad there isn't a way to automatically set the focus to an object like in Bryce. You make a very good point and this should be added to the Vue wish list for the next update of Vue d'Esprit. A very good question and you may get a better answer from e-on software than what has been mentioned here by the moderator. Aperture adjustment would be a great addition to the program and since e-on has many Bryce users it only makes sense. Thanks for bring it up.
