I've implemented the cloud, rain particles, and grass particles into the Evaluation stage of the NNAI thingy. But the real reason I'm posting is to show you my latest 3D model creation. It's a bunch of trip shrooms growing on a mycelium cake (a mixture of grain and vermiculite inoculated with spores for the mycelium to grow). I figure if people buy pot 3D models from me they'll probably buy trip shrooms too. Actually my fish tank model has been the best seller so far.
