I would like to submit this stylized building exercise via a Youtube clip. Is that possible? And if yes, how can I do it? (my attempts didn`t work). Thanx :-)

Hey Henning, there's not really any way to change the format of the exercise to allow that. But, if you made a video I'd like to see it! Just upload the model to Sketchfab and submit that, and include a link to the video in the description.
