bugo would quite easily be the biggest tutorial teaser ever! would love to see you try and get that tutorial done or any rock tutorial for that matter :D .
Not sure if anyone remembers this tutorial or not on rock sculpting, I think this one might help some of you guys out, http://www.thegnomonworkshop.com/store/products/tutorials/vmo01/
Lot of people asked me on how to do a sculpting tutorial of the tiling tutorial I did for this: http://wiki.polycount.com/TilingRockWallBeyer?action=AttachFile&do=view&target=rockwallrender01.jpg I will do my best to describe it soon! It's not difficult, it's just a bit tricky.
I followed that Ryan Kingslien tutorial a few weeks ago. It's a great way to get boulder-esque type sculpts. But not that great for smooth planar cliff like rocks. One thing i did not understand in that tutorial was the purpose of "polygon distribution with the Reproject Higher Subdiv tool" Can you explain a bit what that…
Not sure if you have seen this: http://www.philipk.net/tutorials/modular_rocks/modular_rocks.html Parts of it may of assistance to you. I'll definately be having a crack at this one later...
that tutorial is good, but it doesnt explain so well how to get really hard edges on your sculpt. It does a good job explaining how to use mask alphas tho.
