Ok so i have a terrain generator script that generates terrain using 15x15x15 blocks, ive gotten it to work just fine but...the gameplay with tools weapons etc can't be used because of the lag...Ive been trying to think of a way to reduce the lag but i do not know what i could do? Isn't there a method of rendering with the camera, "making blocks appear in camera when close" but if anyone knows of a solution please let me know :)
