I have previously grown some grass on a terrain in Carrara, and thought I’d try the same in Blender. I didn’t know much about how to do this, but the approach is very similar in Blender.
Like with my Carrara approach, I’ve modelled a few grass stalks from a cylinder first. Those are then replicated over a larger terrain. Neither a replicator nor a terrain generator exists in Blender, so here’s how I did it.
