I think I might develop this one some more but here is my first roll at these crappers.

Nice

Bet you can't roll the same again

Another set I built a couple days ago.
Rendered at home while I was at work.
Preset 10.

Wow, what template did you use for these ones?

Thanks.
Realistic Glass [Light Frosted]

nice dice! great materials...
you may want to try, if interested, the updated SSS material template in the latest release on this scene... see how it goes

and use IOR for plastic instead of glass

Here are the dice with the rubber ball SSS Template.
Nice update btw.

What do you mean by this?

This can get very, very technical...

You can read more about IOR (Index Of Refraction) at Wikipedia...

Index Of Refraction (IOR) is about the way that light passes through different types of materials... diamond, glass, water etc. When a light ray travels through the same volume it follows a straight path. However if it passes from one transparent volume to another, it bends. This is why a straw in water looks bent. The amount of bending differs between materials. The angle by which the ray is bent can be determined by knowing two things: the angle at which the incoming ray has been cast and the Index of Refraction. This IOR value is unique for every material.
Normal Glass has an IOR of about 1.511
Water = 1.332
Air = 1.000
Plastic = 1.460 - 1.55
Plexiglass = 1.488
Nylon = 1.53

By increasing the IOR value for a material, you can control how much the environment behind the transparent object is distorted, and thus improving the realism of the shader.

Thanks for the explanation. I guess I should have asked more specific as I understand what IOR is. Why did you say use it for plastic instead of glass?

I didn't, Fletch did...

I assume that he believes that the IOR value you've used is very close to Glass (1.52) but should be closer to 1.4X...
The rubber ball material is 1.400...
BTW... Forgot to mention that I really like the last render you've made where you've used the rubber ball material...
