Same technique than the previous pack. I used the old pack of rocks I made.
A few instances with some scale variations then let the gravity do the rest. =)
I thought about making a small stream on twitch about this technique & maybe more streams about other things in the future but I'm not sure about the whole thing yet. ^^;
