Whiskey Bottle

As the Cat and Rat film was cut, I spoke to some groups to see if they needed any work doing. Russell Pointer asked if I could create whiskey in a bottle.

He sent me a file with an empty whiskey bottle and asked if I could make it look as though whiskey was inside. This a render of the file Russell sent me:

Firstly, I saw that the label did not look quite right and slightly squashed so I changed the UVs so that it looked more like a real label on Bell's whiskey. 

To add the liquid, I first duplicated the model, made it slightly smaller and deleted some faces to make it look like liquid was not quite to the top. I added a blinn shader, so it had some reflective and refractive properties, and then put it inside the bottle. After adjusting some settings and changing the colour as well as even changing the shader to a phong, this was the result.

The problems with this is that the material is not clear enough so it looks cloudy and unlike whiskey at all. 

I did some research into some mental ray materials which would give a better effect than a bling or phong. I ended up using dielectric materials for the glass and whiskey (changing the colour for the whiskey). These give better control over reflection and refraction and give a more fluid looking shader. 

Using these materials this was the end result.
