Fossilized Crinoid

I had a lot of fun working on this material!
For this one, I really wanted to set a dark Lovecraft / Alien tone to my renders with the disburbing look on this king of fossil.

It was mainly done with substance designer, I just sculpted the heads on Zbrush.

All the tentacles were entirely made with the Ilya Kuzmichev's fantastic curve drawing system , this tool is a must have for substance designer , it's just so powerful!
