Originally, my map geometry was really smooth and had great rolling hills and terrain curves. Well, after alot of editing, moving, twisting, squeezing, deleting, creating, optimizing, etc., it's now pretty messed up. Chamfer is good for individual edges, especially in artificial structures, but not too good for natral terrain. The only other thing I can do is move the verts , edges, and polys individally and try to smooth it by eye-very slow and not very good.
Is there any tool in 3ds max that won't increase the number of polygons, but can take selected polygons (not the entire map. I only want the outdoor terrain, not the structures) and sort of melt them/ smooth them out, and make them more uniform and the geometry rounder?

Thank you!

Select all faces and click Clear in the Smoothing groups rollout.
Then, select the faces with the ground material ID and click group 1. Or, just select all faces and click AutoSmooth and see what happens

I want to edit the actual geometry and make it have more uniform polygons and be smoother. I'll use smoothing groups, and they'll make it look a bit better, but when you're walking over it it will still be bumby, and it'l still look bumby and blocky. I want a tool to smooth it out, but I guess there isn't one.
