Hello Mariola, (It may be worth a shot to post the question in one of the english speaking forums and not in the german one, because there are more active useres, than here. I think the best one would be the "Visualization" Forum (https://communities.bentley.com/products/microstation/microstation_visualization/))I am not sure if you can simply move your post to that forum or if an admin has to do that. Anyways: Are you running a Connect Edition version of Microstation? If yes, then I think it could be an option to look into LumenRT, which is part of the Connect Editions as you can read here: https://communities.bentley.com/products/microstation/f/microstation-announcements-forum/143212/welcome-bentley-lumenrt-designerMaybe have a look into that. What it basically does is that it loads your microstation model and then you can put it in a sourrounding, add people cars or whatever to it and "make it come to live". Also it should be possible to create a "walkthrough or fly-through animation".I have not done any serious anymation with LumenRT, but there surely are people in the visualization forum who may help. Hope this helps to get a first idea where to look for more information.
