Aaron Debalow has created a brilliant new version of his debris plugin (which doesnt just generate debris)
This plugin seems like it would benefit the Archvis community for external detailing and animated visuals. It generates incredibly detailed Brick walls with different brick types, logs twigs, bricks flocks of pigeons flying, loads of really really useful stuff for visuals.
