How are they frown upon? They aren't a huge deal.
i was referring to how he called him an idiot for no reason lol
if it wasn't clear, they're mostly frowned upon in the modding community.
this is largely because they're inefficient. this may not be a big deal with small amounts, but when you get to having more, it gets bad
afaik there's no significant optimizations specially for staticshapes. pre-retail, blockland used static shapes for bricks. i don't know exactly where it began to get slow, but i'm p sure it was about one thousand. consider now that the brick limit is 256,000 in retail.
edit:
lol i just re-said everything zeblote said
