Of course you wouldn’t be able to see all of them on screen at once. The point is you CAN have that much of them placed without crashing the engine. That clustering technique makes it possible. So once you have that much vegetation in a level, even though you don’t see all of them from where you stand, you can walk around like miles and miles and the ones near you appear. It’s to see you don’t really need to worry about the number of vegetation you place into your level.
