Dividing objects into equal parts in AutoCAD or 3DS Max

We're doing a rendering for some condos going in here in Austin and there's a bunch of grass around. I'm trying to use the excellent grass tutorial (since we don't have displacement quite yet) where it shows scattering planes around the surface to create a grass effect.

The only problem is that he scattered 4000 planes across a 1 meter square area and the area of grass I need to scatter onto is 845 square meters. Now the most 3DS Max will let you scatter an object is 65000 times. Using that number, each scatter command can cover about 16 square meters which means I need to divide my 845 square meter area into about 52 equal areas.

Is there a way in 3DS Max to divide it into 52 EQUAL areas? I created it as a Region in AutoCAD and imported it to 3DS Max. Any help is appreciated. Thanks.

Or if anybody knows an unlimited way to scatter the grass planes that would work to. Thanks.

Difficult one to solve, but maybe this little thing can help you.. it's worth a try.

be careful how much grass you use!

The farther you go, the less detail you need.....

Here in miami grass is cheap :lol: (500 sq.ft. of grass is less than $200 and that includes installation and a little bit of grading :wink:)
but when it comes to polygons it can become expensive :shock:

I've seen a few of your renderings that used the technique Leonardo. What did you do to divide up the ground?

well, in this case... I only used a 12'x12' grass path, the rest was a texture

With a little more time, I could probably make it a little less obvious were the polygon grass ends and were texture begins.

in this particular shot I didn't have much grass to model so I cover it all

Yes, use it sparingly only where you need it. The rest, use a texture.
And to divide a polygon you can use tesselate in the edit poly modifier.

Maybe you can scatter the scatter object. :roll:
