Dropping a glass in water

[syberand]

I must have missed something. Where do I change that? Im on the nightly from yesterday.

the isosurface level is hidden in the liquid simulator, but just for case check it in the listener, select the simulator and type $.surflevel the returned value must be 0.5
if the value is correct, we have a problem, i didn't observe grid artifacts on the liquid surface until now. i think we have to look for solution using the mesh, if you have problems on the glass, we can find a way to fix them

[syberand]

The return is 0.5.
If we change it to mesh, how do you suggest we solve it with the glass?

[Ivaylo Katev]

we can add an option to include the wetmap particles to the mesh, this will remove the cavities.
better to see an image rendered with mesh, not sure what exactly is the problem

[syberand]

The implicit


Mesh, no smooth applied

i'm afraid i understand nothing.
what is the surface 1? i suppose it's air.
what are these splash formations marked with 2, and if they are water (not air) why they are visible?
but despite this, i find the mesh render better.

[Ivaylo Katev]

one more evidence there is something wrong - the glass must be almost invisible under water

I think I would have rendered out the sequence in both ways, and blend them in post. I like different parts in both renders.

I think it might be easier if you get your hands on the file

And yes, the mesh look is better, but not so much around the glass

i ran the simulation without foam, simplified the render setup (removed the lights and enabled the environment). your materials are not physical, that's why the glass looks like in air. changed them to be physically correct, and now the single problem is some "ghost" liquid on the glass surface, that is not real water (no particles are existing there), i suppose it's added export time to the grid, will investigate it now

[syberand]

Looking forward to hear what you find out.

i fixed the ghost water layer issue and started a new sim, it takes about 8 hours, hopefully until the end of the day will have the result

[Ivaylo Katev]

the grid artifacts on the gone, but still we have two problems, the first one is the artifacts on the foot, apparently caused by not enough liquid-glass overlapping, the second one is visible only in the simulation, we have beautiful natural bubbles (the foam is currently disabled) that disappear. the reason is the lack of air simulation. we have the option to enable it, but i doubt that it will be so easy, two more hidden options must be involved (currently the advanced options are accessible only via max script). i will continue to play with the scene, until both the problems are resolved

[syberand]

Okay, sounds good. Looking forward to the result.

[Ivaylo Katev]

the progress until now: even with air simulation, was unable to keep the natural bubbles, with low res it works well, will investigate it more.
however the glass-liquid issues are fixed, if the underwater bubbles can't be kept, you can hide them by foam bubbles
