I've always wanted to create grass, so i decided to give it a go. I modeled the whole scene in Blender following one of Andrew Price's tutorials. Patch of grass, bush and trees are provided and they are part of his Grass Essentials pack. Rocket model is downloaded from 3DSky. This is a 50,000 particle system creating the grass and imported into keyshot as individual objects. There are a few mistakes here and there, but i'm done with this for now. Cheers !
