Need to split a large terrain. Any sugestions?

[larsmosnes]

Hi, i just imported a large terrain model from Civil 3d to 3ds max, and uset populate terrain script. Because of the roadmodel beeing placed, i needed it to be 1m pr square. To fit it with the terrain.

 

Now the model is realy heavy, and i whant to split the terrain up inn sections, so i can hide parts of it while working on the model. Is there a spesific way to do this? Whant to keep my model as much as i can as an editable poly.

There are probably scripts that will do this, but if it's a heavy mesh then it might crash or take too long to wait for them to work.

 

I'd suggest manually selecting some of the polys and detaching them. Do this with chunks of the terrain and then put these separate parts on to different layers so you can easily turn them on and off.

Yeah, think this is the way to do it. Gonna try to make the terrain with 5m quads. Detach what i do not need, and then rerun the script for 1m.

If your using Civil 3D split it up in civil then export it to Civil View from the Civil 3D export menu. Then import it into max from the Civil View menu.

 

If the terrain is really big you can create seperate max files with the different partsterrain and xref them together. Then you have great control over turning parts of the terrain on and off and keep you max file smaller.

Use the boundary function of surfaces in order to quickly spit the surface in Civil3D based on specific polylines, this would be more accurate than just selecting mesh portions in MAX.

Thx a lot. This helped alot. Just need to figure out how to make Forest Pack work with a Xref scene... Any ideas on how to do this?

[larsmosnes]

Ahhh, found out that you can create your Forest Pack in the Xref scene, and it will render fine in the main file:)
