>>10013369>>10013371exactly, both, you got it right.
I designed both cars and micro-scale spaceships and even flowing water fountains.
But mostly because of the micro-scale thing. I recently got obsessed with designing micro-scale ships, I designed over a hundred, but over 75% of them only look right with a 1x2 round slope. I can use 1x1 slope pieces in trans colors in certain ships, but if I want to make a ship look sporty, I can only do it with the black piece, or some other dark color in rare occasions.
