flashawd Posted February 4, 2008 Share Posted February 4, 2008 Hi - I have a potential client that want their plastic bottle modelled in 3D and animated to show how it works. I have been playing around w/ the fluids tutorials and all the samples that people have generously posted and it seems that fluids is more designed to work as a faucet, hose, water fountain... anything flowing. Is it possible to have fluid in a bottle for example tip up the bottle and have it flow into a second chamber. I posted a flash anim of the bottle I modelled doing a 360 spin, so you can see the hole in the center that connects the two chambers that I need the fluid to flow through. Any help would be appreciated - even when you check "object collisions" on - it seems to go through mesh. Here is a link to the spinning bottle http://www.flashanimationwebsitedesign.com/rob/rob01.html Thanks, Eric Quote Link to comment Share on other sites More sharing options...
johnl3d Posted February 4, 2008 Share Posted February 4, 2008 try a dense mesh and play with both the size of the fluid particles and the settings and it might work rtry.mov rtry.zip This is a shaded wire frame which seems to almost do what you want and I did not do any major tweaking... to hide some edge leakage (but no fall through !) you could double skin the models outside to hide this that maybe? just a thought as I shut down or ...an animated material....how liquid is the liquid in question...watery or thicker Quote Link to comment Share on other sites More sharing options...
KenH Posted February 4, 2008 Share Posted February 4, 2008 Try flipping the normals of the bottle? Or a double wall? Quote Link to comment Share on other sites More sharing options...
brainmuffin Posted February 4, 2008 Share Posted February 4, 2008 Yeah give double wall a try. from JL3D's test, it looks like a double wall might forgive most of the spill through, (if not all) especially if the mesh is fairly dense.

flashawd Posted February 4, 2008 Author Share Posted February 4, 2008 Thanks for all the suggestions. ;-) That was an interesting idea to flip the normals, but didn't work a I thought it might. http://www.flashanimationwebsitedesign.com/rob/rob03.html And thank you John again for the retry. The problem w/ a double wall is there is a small hole in the center that the fluid is supposed to run through to level it out to an exact amount of liquid in the bottle when you tip in back to a sitting position, so I can't really thickin that up Also, can anything think of another way to animate this - John you mentioned an animated material?? I was thinking I could bring the final render into flash and somehow do it with a shape tween. Anyway, thank for all the help. Quote Link to comment Share on other sites More sharing options...
flashawd Posted February 5, 2008 Author Share Posted February 5, 2008 Just wanted to post the final mockup for anyone that cares. ;-) I was able to take the bottle created in AM and add the fluid in Flash - it didn't come out half bad - I had to modify the fluid graphic 120 time in every frame, and it came out with pretty good results - hopefully my client likes it. Looking forward to a future update to fluids in AM where you can have a sitting fluid. Thanks again for the help. http://www.flashanimationwebsitedesign.com/rob/rob05.html Quote Link to comment Share on other sites More sharing options...
bighop Posted February 6, 2008 Share Posted February 6, 2008 Looks good. How did you do the fluid in Flash? Just key framed? or motion tweened? You could add a button for interaction, just a thought. Nice job! Quote Link to comment Share on other sites More sharing options...
nimblepix Posted February 6, 2008 Share Posted February 6, 2008 Yes, nice job! It cleary shows off the product's feature. Quote Link to comment Share on other sites More sharing options...

flashawd Posted February 6, 2008 Author Share Posted February 6, 2008 Thanks everyone. Bighop - I tried a motion tween and it just wasn't controllable enough. I just started w/ a green square, stretched it and gave it a 30% transparency. Then I had to copy and paste it 120 times and modify for the 10 seconds. It was pretty laborous, but really the only way I could see of doing it. - E Quote Link to comment Share on other sites More sharing options...
jzawacki Posted February 7, 2008 Share Posted February 7, 2008 Looks awesome.. they should be very happy. Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted February 7, 2008 Hash Fellow Share Posted February 7, 2008 It looks good, but I don't understand pasting 120 times in every frame. Quote Link to comment Share on other sites More sharing options...
flashawd Posted February 8, 2008 Author Share Posted February 8, 2008 Robcat - it was odd - I created a square in the first frame and streched it a bit to fill the shape of the lower bottle then I had to copy it - then give the original a transparency of 30% - to do this I had to make it an object (and you cant' stretch an object unless to double click down to the original form - but when you do that - it will change the shape for all version of it). Then I would go to the next frame and paste - the non-object version of it (original) - and strech it a bit to show the fluid moving - then same thing copy it and create it into an object and transpency it. I had to do it over and over for each frame. I tried a motion tween, but it was very uncontrollable - I hope my description made sense to you - not sure it makes sense to me.
