Grass Tutorial

I had some people ask me how to make grass so I thought I’d write a tutorial on it.
Remember that this grass may need to be tweaked for different applications. So don’t be afraid to play around with the settings.

Ok let’s start.

• Add a plane
• Object button
• Physics button
• Click the new button

Now let’s make some grass.

• Make them static. This will make them into strands instead of single particles.
• Up the amount to 5000. But this might need to be changed depending on the size of your plane. Mine was about twice the size of the default plane.
• Click the rand and even buttons. This will make the grass random but evenly spaced.

Now click the particle motion tab. It just above the static button you pushed earlier.

• Change the normal velocity to .005, this pushes the particles up making them look like grass growing up out of the ground.
• Change the random velocity to .003, this adds some randomness to the length and direction since grass is obviously not perfect.
• Make the z force -.01, this will simulate some gravity pulling the grass down.

Now it’s starting to look like grass. Yours should look something like the picture above. If it doesn’t, go back and make sure every thing is set up right.

Now for some texture.
I’m assuming you can add a material and name it grass, so do it. This is the part that will make our grass look very real.

Copy the setting shown below. Make sure the get the strand settings correct, they will make the blades of grass thick at the bottom and thin at the top.

Now grass isn’t all the same color, so we need some texture. I use this one.


Add it and leave all the setting the way they are except change the color to .4

Now if you want some ground under the grass you can add it but putting another plane or object or go back and click the ‘mesh’ button under the ‘static’ button you pushed earlier in the particle options. This will make the plane show up and it will have the texture of the grass.


And that’s it!
