Hi all.

I would like someone help if he or she can do this for my animation.

Here I attached a scene with obj files. I would like to simulate a situation that the water droplets drops into a basin with half-full of water. And I hope some ripples will be simulated too. And It is a looping animation.

Yes I would like to do it by myself using Realflow by Nextlimits but time is limited to me and I am so stupid to learn. I've try using Endomorphs to do that but it is not enough realism. Can somene help me? I cannot pay for that but may be showing credits in my animation for a reward.

Thanks for your attention.

PS: I would like to have LW object sequences for output, for information, please see the attached scene. For contacts and submition please send it to my E-mail by looking at my profile in CGTalk, thanks.

Hey Dick,
Try THIS (http://www.3dtrainingonline.com/examples/ripples.zip). Im using a couple of animated bump maps to do this but you should be able to dissect it and get it working as a displacement or however you want to do it. Its something I threw together quicky but you should be able to adapt it easily enough. :)

Thanks both...

I prefer HowardM's one but when I set the value in MD, the calculation halt... may be it is the scale problem.

I am really an idiot about the dynamic thing, sorry.

I've tried HowardM's scene by replacing his objects and give the ball object a static movement. However, the simulation isn't look like what I wanted.

When the water drops in the basin yes it's water surface looks like the actual thing, i.e. the drop in and bounce back movement...but it has no ring of ripples at all, and there is too much waves......

yeah MD is a bitch, but if you play with it youll get the hang of it.
just change one thing and test, then another, etc.
whats the difference in scale from my scene?
because yes if its drastic (like 10x or more), then your MD numbers must be multiplied...also youll probably need to add more polys to the water.
always remember, if you start from scratch to always use SubDs and set Division order to Last!

I think youll get more ripples if you tweak the Spring.

the problem is once you change one thing, like the weight or strength of the water drop, then your water plane will act totally different, so you need a balance.

here - save this to a txt file and load it in as the water MD Surface

Íname="Floor" wpm=0.25 spring=5000 resistance=5 pesistance=0.75 besistance=0.5 subsp=10 shar=1.5 holdst=100 smooth=2 non_stl=0.75 cstress=0.5 shrink=0.5 self-c sside friction=5 bound=10 bforce=10 fforce=10

see if that is more rippled...also add more polys to the water.
sorry if it doesnt work, all I can say is learn from my scene and reconfigure a new MD from scratch to your scale....or rescale your scene to my MD scene and it should work!
not sure what will happen with the sides of the sink though?
