Hello, I cannot seem to find any posts about this specific effect.
I am not sure if modeling or texturing or a combo of both is the best way to achieve an effect, and what to do for the methods.
I have an idea on the modeling method, but this would be very rendering heavy, so any advise would be great.
I am wanting to take transparent or semi transparent solid materials that have thickness of x amount. And have the inner volume show pockets of defects like air bubbles or cracks / crevis.
I would like it to not steam from the outside surface and be fully floating inside the object.
So this is an example that is somewhat like I am describing, except, I would like the outer shell to not be scratched so when you orbit the crystal you see it is inise.

I guess this would be a good sample to.
Like how the laser inner volume engraving looks.

Thank you.
