Apparently we’re gonna get new visuals for mining roids in the 15 january update : https://updates.eveonline.com/card/5MuXr/visual-update-asteroid-depletion/
I wasn’t expecting anything new about mining visuals but this got more than my attention
EDIT : updated the title, and to those wondering about ice rocks, the animation is a blue-ish smoke coming out of the ice rock while it disappear, I like it.
This new animation only happens at the exact time the asteroid is empty after the last mining cycle applied to it.
