It's a power of 2, not random.
It's a power of 2 * 1000. This is not cool, how about 524288 (or 2
20 = 1048576, so that we have a clean number for the exponent too), which is exactly a power of 2 and around 500k like people are suggesting.
A larger max brickcount would be nice although
peformance boost on large amounts of bricks is key too, i want other people to see the stuff i build and not be horribly affected or laggy
is what I would be wanting much more.
