Homepage website was down/expired/abandoned for this script

Would be great if someone has this script and could upload a mirror download link.

Can you add option in the script to automatically adjust your "default values" to the current system units..Its a bit confusing while changing the values..and theres a limit to the values.. I think the code is written in Centimeter...
When I try to create grass its to small the way my system units is in mm... I know that a simple scale will do after the creation... but if you can add it to the code I think its better.. Thanks nice script

some suggestions if you plan on advancing this script,

maybe add the option for veins especially one along the center,

have the leaf blades able to bend/curve/arc like a real grass blade.

there are a bunch of different type of grasses, bermuda, fescue, rye, tif, turf, zoysia, buffalo, bahia, st augustine, etc.

it would be nice to have some more flavors

All your scriptz are belong to me!

It works just fine (max 2014). Simple and efficient!
For a future version, a good option could be to add some control over the amount of edges (verticaly and horizontaly). And why not, a simple preset material.

Thanks for sharing!

I'll keep this in mind for the future.
I'm collecting all the input people provided and am looking to expand the script with it.

thanks for this script.

can you add an option to remove the middle loop? sometimes we create grass for background and we dont need the edge in the middle.

Thanks for the feedback! :)

Thanks for all the great comments and suggestions!

I'll be looking into expanding the script further with a lot of the suggested features, as soon as they're added I'll be updating it. Could take a while though, bit busy lately, but I'm getting on it for sure! ;)
