I have been trying to make grass for a game i'm developing and have just began creating foliage, in this case the grass. The problem is, i've made the grass as a detailed 3d model with about 20 vertices. I've been trying to render the grass assets using a camera, now i have 2 diffuse maps of the grass from 2 opposing angles. The problem is, i need to render the bump/discplacement textures. The other maps such a specularity can easily be made using photoshop however i can't seem to be able to do this, no matter how much i search for a way. Its not as easy as simply baking cause this is using the camera to render.

Please give answers and thanks
