I'm not new to CGI, but just recently started learning about archviz.
I was always thinking that it's best to add vegetation as cutouts in post since it seems more realistic to me and it oubviously saves a lot of render time. But now most archviz renderings I recently looked at seem to use 3d tree models.
I'm wondering whats the advantage from 3d models over 2d vegetation? Why would someone prefer this method?
