Rendering of a glass of wine (materials and geometry)

[Palee]

Tom!

What about an animated liquid, for example with realflow?

So it's not possible to make a simple glass filled with liquid without a big fake? i'm a little bit disapointed, it should work. Is it a bug or is it the some with other renderers ?

It's exactly the same with other renderers

We had the same problems with liquids in Glas when we where rendering aBottle for a designer. while at that time we where still using final render stage 0, we also fixed the problem by removing the Glas faces inside of the bottle.

So what about liquid animations realflow thats realy a good question.
Final rendre stage (i prefer Vray ) has a solution by by getting each material a Number, which to compute first, for that you dont have to remove the wrong faces.

maybe a nice task for Vlado ?

This is not going to help you for animated liquids, since the geometry of the liquid and the glass will be different in general and the two surfaces will not match.

Vlado :

Could you explain to us in a simple way why all/most of the renderers do this ?

Thanks

Hallo Vlado

i am not sure you are right so i will test it maybe later

now maybe another solution for animated liquids ,also difficult,

you process the simmulation of your liquid in motion in the way it has a little more vollume than the glass. after this you try an animated bolean that automaticaly removes the glass material on the inside of the glass.

i didnt try it yet, and also everyone knows how bad boleans in max work
but maybe it is worth a try as long as there are no other workarounds for animated liquids in glass and as long as only removing the glass faces at the inside bring a perfect result.

why on earth would there be a problem using realflow to pour a liquid?

[flipside]

The problem is to render it, not the animation itsself. With animated liquid, the liquid part will always keep a smaal distance between the glass and liquid, and the rendered result will look wrong (see post above)

I'd love to see your idea in motion Tom, hope your serious about trying it.

[tom schuelke]

Hallo RErender

Well i will try it. doesnt look that easey. But i´ve got a little two and a half year old son. so i´ll have to play other things this weekend

next week i´ll try it. if not you can remember me.


greetings Tom

I've been adding some improvements to the refraction of the VRay material; this is the result so far:



I don't think we'll implement surface priorities as in fR, since that would be too complicated at this point. Still you can get the result above even without this feature.

Best regards,

[Psy]

nice, when can we expect to dl that scene so as to see how you achieved that result?

providing that those features are out in the next version.

[3dform]

have anybody tried a rendering with dobblesided and reflect on back side turned off?

Yes!! it would be very nice to have that file Vlado, can u make it available to us?

I have the solution:
