This file includes five level-seven Sierpinski Gaskets, each made with 78,125 pyramids, stacked to form a level-eight Gasket, which has 390,625 pyramids. I have stacked them up to a level-ten, which consists of 9,765,625 pyramids. Never tried stacking five of them to make a level-eleven (48,828,125 pyramids), but you're welcome to give it a go. Feel free to use this for any purpose you would like.
Yeah i easily stacked it further but man was it slow to move the camera for shots due to its size. Great job! Enjoy my 10K render: https://cardse.net/image/sierpinski-triangle-10k-render.cSD
