I have never figured this out, so I thought I'd post this.

I do a lot of product rendering, mostly in the beverage field.
A good many times, the client wants something that looks cool and refreshing, with their product covered in water droplets (i.e. sweat).
Can't quite make that happen in my renders, so I have to do a ton of post production.

Came across a tutorial for "sweat" in one of the NewTek forums...
ftp://ftp.newtek.com/pub/LightWave/Tutorials/Vidz/SweatTech.mov

Great technique for getting the particles over the surface...
but when I apply the HyperVoxel surface to the particles, things start falling apart.
The HV's look like they do a Boolean cut into the surface, so the "drops" come across looking black, since they are basically refracting the inside of the main object.
Is there any way of preventing this?
Or is there a better technique for sweating a bottle of pop?

Thanks

Are you using vpr for render?

another thing, add some reflection 50& perhaps and try that, so the drops reflect the environment at little, but I think you should throw in a textured environment image of the sky, or use hdr images.

It seems to work here.

I used the glass preset for the HVs and the only thing I changed was the IOR.

Be sure to check the render settings too.
