Crystals man.....
show user profile  OmniMan49
Im working on a project using Vray. Does anyone know of
a material workflow to produce an effect similar to the beautiful Silestone commercial
here:
http://vimeo.com/17325731

Im referencing the crystals and looking for two things.
1. Any key words for the "creating depth inside the crystal" effect without modeling the inside of simple geometry.This is so i can narrow down my search for materials.
2. Any available tutorials that exist out there that cover a similar effect?

A further explaination would be to achieve the effect of complex geometry within simple shapes.
I feel like im missing a key word for this so thats the best explaination i have.

thanks guys!

I'm not sure what you mean by creating depth without modelling the inside of simple geometry.
Do you mean like fractures and stuff that pass through the inside of the crystal that are visible? I don tknow why anything would need to be modeled inside geometry, unless there are thingies inside that are to be seen. Can you give some specific pics?

You talking about modelling the "filling" on the inside like in these pics?


I'd say just a map if you wanted to be cheap, but it wouldnt animate well at all. Or a combination of volumentrics and geometry.

Yep! thats exactly what i mean. Strange thing is they seem so organic that its hard to find a way to make them from polygons... Especially when i will be dealing with a good amount of them....

Volumetrics eh? In vray how could you apply this?

Ill update with WIP pics throughout the process

I'd probably go with an exterior polygonal shape and an interior one -or more-, maybe some cracks modeled also, with scratched opacity maps, etc.

Cheers,

there used to be a tutorial for vray to achieve this, do a google search on vray ice tutorial

Here it is :)

I did a few experiments from the tutorial, worked really nicely for its simplicity. :) Probably not exactly what you were after, as it hasn't really got any depth as such, more of a surface cheat , but can still be quite convincing. Here's my efforts. :)

OH WOW, And holy cow! Nice work on those crystals... after a bit of time spent ive been getting a very similar result as your renders... unfortunately i cant show them as of right now.... but i promise to show updat. Ive actually had pretty great results with using a vray blent mtl with a vrayfastsss shader as the base, and additive layer of reflection and refraction as. Also a detailed displacement map helps a bunch too. Thanks guys for the help so far!
