Hello,

I see a number of tutorials on how to create good looking grasses when creating 3D renders but can't think how to model it for realtime/use in a game's scenery.

Sure simple models with alpha cutouts can be used to create plants and trees in really awesome scenery but what about a lawn?

Are there any good tricks to achieve this effect? I tried with a simple 4 sided box and a small texture and the number of objects needed for a decent appearance made Max crawl to a halt.

(I am thinking it may be possible with a shader but that is a whole other area so thought I would just ask about anyones experience with modelling it here)

Thanks!
