Bubbles and fizz in liquid - still render C5 - Polyloop

Aunty Betty · 28th October 2007, 18:03

I'm tring to find a simple way to add a little touch of fizz/ bubbles in liquid in a glass to add a little touch of believability any suggestions the best way to go about this?

At the moment I have the glass surface and the liquid surface , each with suitable shaders.

You could try making a surface slightly set in from the insideof the glass, then use the surface replicator to place little balls on it as the bubbles. Never tried this technique, but it should work i think...

Thanks jb - that would be a cute cheat.

or play about with a particle emitter sending "bubbles" upwards ?

fizzy.zip is the car file (v5)

Following JBShorty idea made some example.

I put object - tubes - inside glass and applied Surface Replicator.
And here is result.
In .zip file is .car scene.

an attempt at foam/froth using a displaced cylinder with an alphamap.

file in zip.

I like that jowra - and I bet that is a lot more controllable than using emitters.

anyway I think I might need to go and do some more "Foam" research - shesh ! the things I do for my art

edit the png is just showing up as a white screen ? i've no idea what I've done wrong there ?
