Im about to make a bottle of beer, but i've never really done any material for liquid substances before and it's a bit tricky for me to get the right feeling...

I started of making the glass for the bottle and i'm pretty satisfied with it. Now, for the liquid beer substance, I just don't seem able to get it right. So, anyone with experience - please help me out?

This link show the rendering:

And this are the settings:

As you can see, it looks more like dirty water than beer. This is a raytrace material and i've rendered it with the mental ray-motor.

I've tried to modify it with a radial gradient on the diffuse, but it didnt do much difference really...

I put a falloff in the reflect map and a bitmap instead of the white color (an earlier tip i got). I use a falloff for the transparency map.. Thats it. Now, were do I put the magic to make this work? :S

the problem with beer is that your references are the beautifully lit, carefully styled images that come out of advertising photography-- in other words, what beer "looks like" has a standard set by meticulous commercial photographers. . .

you didn't say whether your beer was still or to be animated. . .the solution required will vary greatly depending on which it is . . .

I agree at crocodilian's reply, note on the end product to be an animated one or a simple, static image.

If it is a static image then you could try and not use a separate object for the liquor. Invert the object faces on a sufficient level on the bottle, and slap in a transparent yellowish raytrace material.

ff image rendered with brazil rio, i dont know much of vray renderers since i only have max5.
