water splash...

[fabmedia]

I have a client that wants to have a water splash background with a "frosted" bottle. What they have is a water bottle that they want to market.

Here are some examples.

I'm not too sure where to start or how to achieve it properly. Any ideas?

Thanks,
Arlen

Hi firstly work out the profile of your bottle then revolve it and tweak in modeler. You can achieve the condensation effect by utilizing the outside surface generated by the lathe almost like a skin and apply a water drop bump map, that you can create it PShop.

Or if you really want to impress use the particle fx to create water drops running down the bottle?

I'll see if I can get some links here:rolleyes:

Hi there

is this a still or an animated piece?

the type of water splash in the examples smacks of particles and hypervoxels to me I'd check out flay.com and lightwave tutorials on the web

like Luka I'll see if I can turn up some links too

Well I happened to try this for a test, using HV. It's not an animation, but is a still for a print image for a water bottle so this is my test.... http://209.121.25.146/watertest.mp4

if it's not moving then you can make it by spraying points exactly where you want them in modeller then use the points instead of the particles for your hypervoxels so you can sort of model the splash. Have a few layers so you can apply different hypervoxel sizes to them for that solid water/water zingy spray look

Hmmm... never thought of that. BUT this project might lead the way open for a commercial... but I guess I can always leave that for later.

Thanks for the great idea. I tell you, I've learned so much from taking part in these forums. Cool!

Arlen

[fabmedia]

Okay, here's one that's more "believable". I played with the settings and moved the emitter instead of the collision object.

Let me know is this works...

Again, only one pass.

Is it good to keep the particles small?

Arlen

[munky]

I'd suggest using at least one more emmiter but keep the size of the hyper voxels small to add a bit more spray around the outside of the main flow

Okay, smaller particles, good. I'm having some problems with the object that I'm trying to bounce the particles on. What's happening is that the particles are going throught the object. Now the object is a subpatch item and I'm using the FX_collision custom object under the Object Properties. I have it set to sub-patch, and I've tried to do a bunch of different things like increase the size of the particles, but they move away from the object itself and don't touch it.

I'm not too sure what to do. I can post images if anyone wants to see them.

For what it's worth do a search on the forum and here's a link that I found

I think you are on the right track

[fabmedia]

Okay I've been working on this for a couple of hours today. It's all particles....

It's just phong shading. 12.1 seconds.

I still have to add some watter on the bottle itself and a bit of a splash on the front as well.

Hi Fabmedia,

Is there a tutorial anywhere on the water
efx you're getting? It's looking very cool.

I need to get something similar for an upcoming project.

Thanks,

Carl

[fabmedia]

Actually no. I guess I'll have to write one. There's really nothing to it. Lot's of trial and error.

I'll keep you posted.

Arlen

FWIW

I like the water alot, fabmedia! It's cool! I wouldn't mind seeing a tutorial/white paper/brief bullet list on the how-to of this thing myself.

[fabmedia]

FWIW?

What the heck is that?


Arlen

[ckeyes]

Hi Arlen,

Is that just one emitter? I haven't been able to reproduce anything even very close to that
look with the smaller slower moving drops etc.

Frustrating stuff sometimes...

Carl

[fabmedia]

No it's not just one emitter. The latest image http://209.121.25.146/bottle9.jpg uses 7 emitters. In the back there is four. One that uses a small number of particles that are big to give the body of the splash. Then I cloned the emitter three times and adjusted the number of particles, the explosive and vibration settings and made the particles smaller. The trick that I found was that the smaller particles needed a large randomness in size that would give the variations that were needed.

The front splash used three emitters that used smaller particles than the back so that it looked relatively the same. I'm still not finished the image which is going to be used to launch a the new product. So I don't need to worry about animating this (thank god!). But what i don't think that I would need to change the settings all that much.

Does that answer your question?

Arlen

[ckeyes]

Thanks Arlen. Really appreciate your help.
I think armed with that I should get close
enough to what I need.

FWIW means "For What It's Worth" in shortcut, webspeak.

[fabmedia]

Right. Thanks!

Here's another...

much better. I think the round voxel at the top left of the bottle is too... big and round. Very kewl none the less. I've got an animation of a pretend comercial that might help out, its at:

www.zachtv.com/home.php?zpage=FILMVIDEO&img_butt=powpow&gal_img=powpow_1

click the big picture to download the divx file. I'll give you the scene file to mess with too if you want.

you're doing great.

[fabmedia]

Okay, I think I'm done... what do you think?

how about a few droplets on the black top to blend it in more? and maybe look at the background colour.

looks great though

paul

[ckeyes]

Very cool. The drops at the top right seem to stand out a bit much. Maybe from being relatively stagnant and all about the same size? Just my .02.

Carl

[Matt]

Fab - very cool, that image wouldn't look out of place in the gallery if you ask me!

[fabmedia]

Wow. I've never had anyone say that before. I wonder if I should?

Arlen

[ckeyes]

Gets my vote!

Carl

[Zach]

Definately very kewl!

I wouldn't mind if the bottom of the black lid didn't look so sharp. Other than that, Perfecto!

[Matt]

thing is, the cap is an injection moulded part, the sharp edge is where the two tools that mould it come apart, so there would be a sharp edge there in reality!

[fabmedia]

That is very true. Infact, it's slightly jagged in areas. But I can see the viewpoint though. I have noticed that it's easy to make something 'perfect', but hard to make it real.

In a strange way it does and doesn't make sense.

Arlen

[fabmedia]

I'm going to ask now if everyone agrees whether I should submit the water bottle to the Lightwave gallery.

I'm being ultra serious...

I think it looks great. Post it!

Carl

[Matt]

Dude just post it!

Even I posted something ages ago, never turned up though! Guess it wasn't good enough! But hey all you can do is try!

:)

[anieves]

just submit it. I think it looks great. What's the worst thing that could happen? ;)

[fig]

go for it, i was actually thinking that before someone else suggested it. looks awesome :)

chris

[Rory_L]

Submit!

(I like submissive people! :) )

R

[fabmedia]

don't even go there. My wife doesn't like competition.

=)

It looks then like I will submit the image for the gallery and cross my fingers.

Cheers!

Ahh, I remember the old days of trying to get splashes...

Warning: Really Old Renders!

I'm the second pic :)

[fabmedia]

Hey... looks great! Did you use nurbs or metaballs? I was considering using metaballs or modeling the main splash body, but I figured that it would take too much time.

Arlen

[kilikili]

No metaballs or metanurbs, just manipulating a mesh and deforming a bunch of spheres till I was satisfied.

Gosh, that was a long time ago....

[luka]

yes submit it, you've done an exellent job
