What is the recommended way to create grass cells on a 3d grid map without too much performance cost?
I've been experimenting with multimeshes with PNG grass textures on them but performance suffered horribly. I've also tried instancing dozens of those PNG-textured meshes (basically, everywhere I had a 'grass' cell) and it was a little better but still caused huge performance drops. I keep seeing games on Steam with lush grass and other vegetation covering large patches of terrain with seemingly no FPS cost. How is this achieved?
