Any tips on animating a liquid?
Thanks!

Well there's one way that you could educate yourself on how water acts... study various liquid reactions using blenders liquid simulation.

It's not that difficult, but can take a while to bake.

Or you could just import the many different shapes of the water inside blender.
Which is how I got this:

Some more advanced 3D animation packages include liquid simulations, such as Blender for example.  From what I can gather the simulator can define the motion of individual vertexes within a surface mesh, based on the physics equations of fluid motion and refined by user-defined parameters.  I imagine it would be possible for somebody with a much better grasp of programming than myself to construct an Anim8or script that could do something similar, perhaps defining a stream of morph targets.

Without such a simulator you are on your own mate!  It really depends on what sort of liquid you want to animate, whether it is close-up water gushing from a tap or a distantly-viewed ocean scene, for example.

short of learning a new program or how to program, i belive your answer lies in morphs.

I most warn you on using watergen, the program headwax just gave, it's very unstable imo.
Save your work often and keep a backup when you use it, because it easily corrupts your files.
Still it's a good program for create liquid simulations.

terranim8or works too. I think its in the resources tab on this site. It's quick learning from the tutorials provided

hya floyd, it's not bad if you stay away from the bones.... the directions are the clue to using it. They are actually pretty good directions...

Jam, other way is to extrapolate different meshes form the same path and use 'morphenvy" to use the different meshes you have generated as morph targets...

you make your path, then copy it a few times to different objects, then you push and pull it how you want then use build>extrude on each path using the same length and seg parameters then use morph envy to morph between each different morph target......

hmm sounds hard doesn't it...

a quick example of this method (the wave not the stupid gmail logo)




here's another method

done by expanding the water rings with morphs

I so badly want to learn to use blender , but its user interface is just so hard and the program is just too complicated. Anim8or is easy to use for me , i'ts easy yet functional , I love the user interface . But all the people say that blender is the best and so on, I don't know witch one to choose Anim8or? , Blender? (And another thing they don't understand is that Anim8or is now just at v0.97d and blender is at v2.48 , Anim8or is being built by One man and blender started developing before anim8or so they can't realy compare the 2 , but anyway I still don't know witch one 2 choose??? ,I don't realy know the power of blender,can anyone advise me on witch one I should use?,but what i've realised is that theres a relation between all animation programs , Point edit and so on.?)

My knowledge of Blender is limited to published animations made within it, so I can't comment on it's abilities, except to say that it has a reputation for having some quite excellent features within a complex interface, as you say.  My advice to you would be to learn how to use Blender, and any other animation/3D modelling/2D editing packages you are able to access, and add this knowledge to your Anim8or skills.  This way you will have a powerful toolkit to enable you to create whatever springs forth from your imagination.  There is no need to restrict yourself to any one package, and you would be doing yourself a dis-service by doing so.  As you suggest, all 3D modellers share the fundamentals of wireframe construction, and in general these wireframes can be exported/imported between packages.

I personally use Anim8or for modelling and UV mapping, and Carrara for scene composition and rendering, because I believe this makes use of both packages' best features.  There are certain Anim8or features that I miss in Carrara (animation on/off button, sequence mode) but Carrara has things like physics, inverse kinematics, hair simulation, particle effects, quick renderer etc. which make it the better choice for rigging and rendering.

by the way blender is also open source so hundreds of people can add to it in addition to the company thta makes it

but anyway use a combination of 3d apps i usse 3ds max zbrush(trial) and anim8or. for all my stuff although i am trying to still learn blender

whatever works

by the way Anton you can edit a post if you misspelled something that you want to fix instyead of making a new one
