TheSpleen Posted March 18, 2010 Posted March 18, 2010 What I would like is to be able to make small leaks of different strengths throughout my Ark. And on this possible title clip I am wanting a splash of water hitting the Earth, but not alot. Like when someone throws a drink in another persons face. The Earth is that face and I want it to splash and drip. Is that possible? Point me in the direction if this is feasable? Tutorial? Thanks! Gene title2.mov Quote
largento Posted March 19, 2010 Posted March 19, 2010 I can't offer too much of an assist, but my first thought is that a sprite emitter would be the way to go for the high-pressure leaks. I really haven't gotten my feet wet with fluids yet (pun intended.) :-) Quote

largento Posted March 19, 2010 Posted March 19, 2010 You'd have to experiment, but one thing to try might be to put a container shape under the emitter and then animate it like you would the glass if you were throwing a glass of water in someone's face. Give it some time to "fill up" first. Quote
TheSpleen Posted March 19, 2010 Author Posted March 19, 2010 but how do I make water? where do I start? Quote
NancyGormezano Posted March 19, 2010 Posted March 19, 2010 but how do I make water? where do I start? There is water and then there is water... I haven't really played with liquids - here's one tutorial here's BigBoote's quickie intro to fluids John the Bigboote Campbell Soupie-Floopie man - also has done a video - use search on "liquids" and ye shall find - And then again - there is cloth, or just making a surface and displacing cps - all depends on whatcha wants to do.

largento Posted March 19, 2010 Posted March 19, 2010 Hey Gene, the really short version is that you create a material and change the attribute type to fluids. Then you create a model with at least one patch and apply that material to it. That will create an emitter that you can place in your choreography. Fiddling with all of the settings is the time consuming part. Quote
Paul Forwood Posted March 20, 2010 Posted March 20, 2010 You could do something like this: MarsSplash_360__A06.mov This is just a really rough attempt at testing the concept but with some care you could do some effective splashes that would fit well with your syle. Quote
TheSpleen Posted March 20, 2010 Author Posted March 20, 2010 but how do I make water? where do I start? I'm biting my tongue. that sounds like the painful way but I'll try it. Quote
jimd Posted March 20, 2010 Posted March 20, 2010 but how do I make water? where do I start? I'm biting my tongue. that sounds like the painful way but I'll try it. give this a try mess with the material settings to change the fluid BIG_DRIP.zip Quote
johnl3d Posted March 21, 2010 Posted March 21, 2010 Bit late here is my quick attempt...modified gravity forces as well as material...sorry but have not played with fluid for a while wetface.mov slightly different view awetface.mov awetface.prj decal not included a quick tweak a_wetface.mov a_wetface.prj Quote
TheSpleen Posted March 21, 2010 Author Posted March 21, 2010 example EARTH3.prj w.mov Awesome! it's missing the earth tga but it's perfect! Quote
Paul Forwood Posted March 21, 2010 Posted March 21, 2010 Fluids are very memory and CPU intensive! I think Serge has an i7 with lots of RAM. (Lucky guy!) You could try turning down the number of particles until you get to a stage where A:M stops crashing. ------------ Edit: I see what is happening now. The project opens with particles turned on and the frame counter at 01:00. This means that you will have to wait for A:M to calculate and plot all of the fluid particles for the whole animation before you will be given control. Just wait and then immediately turn off particles. Make sure that they are turned off in any other windows that you may have open! Save the project now to ensure that it opens with particles off next time. Leave particles off until you have turned down the Rate of Emission and then try turning particles on again in just one window. Find the level that your machine can handle and then render to see if the effect still stands up. If not then play with the properties. In Serge's example I think that you can turn initial velocity right down to 0 because the liquid is just being collected in the container. Quote
serg2 Posted March 21, 2010 Posted March 21, 2010 I have i7 870 RAM 4 G Light version prj EARTH4.prj I do not understand why in a camera view occurs clipping (Particles are cut off by square area) Thank Quote

TheSpleen Posted March 21, 2010 Author Posted March 21, 2010 trying a 10 second render of his prj file first frame at 4 hours and counting, must be figuring out all 10 seconds AM does seem to be running as the little alien guys are constantly beating each other. I will let it run and see what happens. Once initial frame is done rest should go faster. Quote
HomeSlice Posted March 22, 2010 Posted March 22, 2010 When doing test renders just to see what is happening, it helps to render at the lowest resolution you can get away with while still being able to see what tis going on. Also, rendering multipass with 1 pass speeds things up to. I do not understand why in a camera view occurs clipping (Particles are cut off by square area) I think I read this is a new feature Steffen added to that latest A:M (15J+). It is supposed to help speed up fluids in real time I think. Quote
serg2 Posted March 22, 2010 Posted March 22, 2010 I am am confused with a trimming artefact at render (red line in www.mov) EARTH9.prj ww.mov www.mov Quote

HomeSlice Posted March 22, 2010 Posted March 22, 2010 I am am confused with a trimming artefact at render (red line in www.mov) That is strange. I don't know why that happens. Maybe post this issue in its own thread and hope Yoda will see it? Quote
serg2 Posted March 22, 2010 Posted March 22, 2010 Particles are cut off because of the included parametre "Clipping to visible viewport = ON" video without clipping: w_wcrop.mov On the rests of drops on sphere it is possible to notice that water is not linked (not glued) to rotating sphere though flows down on it Quote
Paul Forwood Posted March 24, 2010 Posted March 24, 2010 Fluids are tricky! I have played around wiht this so much and have had frozen renders for about 90% of my attempts. I have had to turn off alot of surface properties and have reduced the rate of emissions to just 300 diminishing to 0 over about 3 frames. I haven't figured out what causes the freeze for sure but it is probably a combination of settings. This was my last attempt: Drips_AM01_k.mov Not great but has potential. -------------------------------- Edit: This one is a little better. Slightly more particles and I animated the "Cull Particles" property so that the splash would look more like a splash. Drips_AM01_l.mov Quote
TheSpleen Posted March 24, 2010 Author Posted March 24, 2010 I been experimenting too. fluids are very touchy. Quote
