Direct hit, pow!
I did try alternative snow objects, but bloody hell I failed badly lol. First I tried this mine, it was white, but in-game it looked like a black mine falling, 'thud'. Then I used a plane object for fun, dodging planes is fun lol
Hmmm. I'm wondering if there is a way to keep the height away from the track, for example destroy the object before it gets low to the ground, unsure of how it will look, but I'm quite certain it will stop the slams.
