How do you do this?

I'm going through this tutorial: http://www.3dtotal.com//team/Tutorials_3/joy_tree/joy_tree_02.php and I'm not sure how to make this interesting pattern here. I'm guessing some sort of array? I've never had to do something like this before, would someone mind walking me through it? I already have my grass, just wondering how it's laid out like that. Thanks.

looks like a single long rectangle that fits the grass UV space once vertically, but extends well past the edges of the UV box so that the texture is tiled horizontally many times. imagine a telephone poll fallen on its side and it coveres the grass on the UV sheet.

Once that's done the Pivot point was set at one end of the rectangle so when duplicated and rotated it would center on one end. Duplicate as necessary as you ratate. Many can be slelected and rotated to speed up the process as you make more.

/facepalm. Why didn't I think of that. I guess I was thinking too hard. Thanks for the help crazyfingers.

this seems like a silly method to get a field though, as the density of grass will be far greater at the pivot point, than it is at the far side. You can see this pretty clearly even in the example image.

Doing grass, tiled on a long plane is somewhat standard, but I would be more likely to make a small cluster of those planes, in some fairly random pattern, and then clone that around instead.

in maya i would just press shift+d, rotate the mesh, and keep pressing shift+d because it saves your last rotation sequence.

Tumberboy, it will only be viewed on the side like the bottom portion of the image above looks like. I guess it's a quick way to give depth and slightly rotate the grass a bit so that it looks different instead of the same grass image over and over.

Like Nick said, grass clumps randomly scattered around. BUT also use a randomized object painter script that references a library of grass clumps would be my way forward.

I personally like Niel Blevins object painter script, it has one click placement which is great. Painting tends to create a lot of extra geometry that has to be later culled back out. There are other scripts out there, the maxscript help file even has a tutorial on how to do it if you wanted to make your own, which I guess is where a bunch of these probably got their start ha!

Out of topic, but oh the image 16 looks so much better then the final....

But I agree, don't see the relevance of that method.
