How to make Crystals

Inspiration

If you take a little bit from each tutorial, like the driver part from the first one, the texture the intermediate one, and the volume absorbtion from the last one.  You should have a very good looking crystal.

Idea for the shot:

So, thinking about that shot, need some asteroids, debris, a broken ship, more debris, a salvage ship, an astronaut with a spot light,  and something that tells what happened to the derelict

Elements needed:  Debris, asteroids, broken ship, salvage ship, astronaut

Tutorials used:

Make the ship

Chris has put out quite a few tutorials that are easy to follow.  

This is a tutorial from 2.7, but the ideas should work with shaders in 2.9.  Very nice style
