Forgot how to export terrain into 3ds max properly...

[TheBuilder]

A few months ago, I made a lot of levels with terrain, exported the terrains as an obj file to 3dsmax, then imported it back in to UDK without any problems, so it would work on iOS.

I'm now trying to do that again for new levels, but the problem is that it's a while ago since last time, and I forgot how to do it correctly... When I export it to 3dsmax, each polygon is spilt up for some reason. Earlier, the whole mesh got selected when I clicked on it with element checked. Now only a polygon.

This makes the whole thing have triple as many vertices than triangles (unecessary increasing the file size), and the UV maps get messed up. I just can't figure out why I can't do it anymore, and I was stupid and lost those files where I had the old orginal terrain chunks, so I can't look back at what I did... Anyone have any clues?

Bah, this is making me crazy, no one knows how I can fix this? I'm pretty sure I didn't do anything special earlier, yet it split up each polygon...

It looks like I somehow solved the problem. I found one of my old files and the same happened there, except I did reduce length, width and U,V,W tiles in the UVW Mapping modifier, which apearently reduced the amount of verts. While I still don't really know whats really going on, my problem is solved.

Use the FBX format if you are using Autodesk Products like Max / Maya, it may help

Once you are done with the UVW mapping apply a smoothing modifier with one smoothing group. Then Export Using FBX with the export smoothing(?) option checked. This should avoid unnecessary vertices being added by UDK.
