A quick tutorial on how to have grass automatically be placed via a material instead of placing manually. A troubleshooting tip, if your grass is not rendering, check your landscape streaming proxy as for some reason it sometimes doesn't update from the main landscape material. This means manually placing your material into the streaming proxy tile. A quick and easy way to do this is via Window -> Levels -> Summon World Composition and choosing landscape tiles. (careful as you can move the tiles around in this window).
