I just wondered what would be the the most effective way to do tunnels (like 2fort sewer), which would create nasty visleaves otherwise. Func_detail or displacements seems to be the obvious way, but I'm not quite sure how generously I should use hint brushes to split up the leaves.
Should the tunnel be completely surrounded by either world brushes or hints, or is there any better solution? (what about nodraw brushes, for example?)
