Unify Normals

[glorybound]

I have a site plan and the normals point in all different directions. The site is flat; how do I point all normals up? I thought unify normals is the solution, but not!

[super gnu]

either manual edit, or if its a real mess and you are pressed for time, double sided materials

to be honest ive never been sure if "unify normals" actually does anything at all. maybe there is a script that does better job.

what we sometimes do is just apply a shell modifier with a couple of mm on both sides, works well in most cases

Redo the site with Populate Terrain, nice little script

Edit Poly, turn ignore backfacing on, go to top view, drag out marquee selection, press Flip.

[super gnu]

ha.. yes.. as Dave said, if the terrain is flat, with no kerbs or other non-relatively-horizontal polys, this should work fine

Populate Terrain, I love it and this is why I am trying to fix my normals. When I use it, it fails.

I am trying it right now!

Does populate terrain work with Max2015? I keep a copy of max2012 installed just for populate. Would be nice to get rid of it...

Sorry for hijacking!

It does work, I used it on max 2015 and I'm currently using it on 2016 without any problems.

Excellent!
