Talking Champane anyone with bubbles ???


Well I used a glass shader for a wine glass then I got an idea from a tutorial using some older glass shader
(complex) but I stole the refraction index for water that is 1.33 and the glass was set to 1.55. So I worked of of that then I though "Bubbles I need bubbles" so I did some spheres then shrunk then copied then copied and so on. Then I lowered the poly count down alot. Then I found this from google http://www.darksim.com/dswiki_new/index.php/Refraction So I did that for the bubbles. For champane I took the innner shape that fits inside of the glass then changed reflection color color and so on to a yellow ...

I am still working on getting in more bubbles more realistically. I'll do more bubbles and improvements based on suggestions.
Well Hope that was not bad for being 15 + anewbie who just started Maya :bow:

"Call me bubbles darling, everybody does!"

"Champagne, Champagne for everyone"

-Sorry about that

The images you posted are a bit too small to see any flaws.... or maybe thats your master plane

Anyway, from what I can see, everything is looking shipshape!

Nice work!... Champagne?

The flaw is very eay to spot unrendered but rendered I can't find it for a $100 unlees I got better higher resolution images. If anyone wanta to do what I did I can do a quick little explaination.

should raise the poly count of those delete all but one and use an instance. It'll look better and have a lower poly count in the end. Looks good though. Mabey some foam?

Post a bigger image if you can, I'd like to see what they look like - I'm making props just now and plan on having some liquids in the scene.

Also, an instanced piece of geometry will still increase the poly count.

I would look at other solutions than using more and more geometry. Try a solution with Maya Dynamics and Fluids to get the look you want. I am sure there must be one out there fro bubbles in liquid/fluid. I am the same we need screens of about 640x480 to be able to crit or look at, these are far too small to make out anything.

A little lost I am sorta new to all of this,I did not do a full view since I have not put bubbles around the top correctly,
I'll have to do some dynamics tutorials since I am completely lost about your suggestion. I could also just do more bubbles to fill the glass better then for foam make very very small bubbles then sorta make foam.

If you are just using a dialectic material for the liquid then some sphere particals released from a hidden duplicate of the faces around the inside of the glass at a very low rate would not be a bad start. if you make it so they have to collide with the glass but have no bounce and a lot of friction, some should even stick to the sides in a realistic matter. As for the ones on the edge of the liquid surface/glass border, a circular goal object should work just fine.

If that doesn't make any sense, then yes, you should look at some tutorials.

Sorry I have almost done all the maya tutorials but noy dynamics since I am tryign to improve the skills I have now,
I used a glass shader with a different refraction indeax. Well I'll keep reading and learning then try again with some moving bubbles.
