hi everyone ..

can anyone pls help me on some techniques bout melting an ice cube .. in a realistic manner ..

ive tried the HOW TO on the AW site ..

ive got the look for the cube ..
but am havin problems animating the melt..

any HELP is really appreciated..

you could use lots of blobby surface particles with a texture of that image projected on them.... i think its possible but ive never done it before

a simpler way... make it a softbody and put gravity on it ;) though it might not look as realistic

How bout a poly shape morphing into a puddle, and emitting water drops.

Hmm..can you morph a soft/ridgid body?

what about using a.... *shudders* bolean, with a world projected 3d texture in the displacement channel on a cube that's subtracting from your ice cube... then simply move the subtracting cube down, use subd's on the resultant mess to smooth. it's a possibility that might give quite nice effects.

My guess would be to use blend shapes to make it appear to melt and particles for the water that comes off it. Goodluck.

hi there,


I have one suggession. Your Ice cube looks good, but I have one Idea that you can try. You can put one more box over this ice cube, with high specular, with high refraction and very small bump at places. This inner icecube will be more white and more transparent with some bump and irregularity. Try that render and you should see a lot more realistic icecube, though it will play big on your rendertime.

As far as melting goes, ive never tried this, but using softbodies, gravity and some nice fileds should give nice results. here too i suggest using two objects, one to become water after melting and the other one to melt more slowly, which itself will be the melting icecube. One object (the water object) will start at the bottom of the icecube and starts expanding to simulate water.
The other is the icecube itself. which melts slowly as the water expand. To melt this icecube, as i said use softbodies and low gravity value and some rigid body collisions with high dampling should give it the subtle irregular melting. you can also use different fields instead of rigid bodies.
I hope what i said works.

good luck!

this is my first post ever and uve all been showing good response ...

i really really really appreciate ..

thanks again ..


Happiness always

isnt there a melt command or something? or am i thinking of messiah animate?

hmmmm....... why not use softbody dynamics?
make the ice cube to be softbody, attach gravity to it. and make the floor to be colide with the ice. and make a gradient mask to blend the water material to the lower portion of the ice cube. and of course u've to animate the mask to make the animation believable.
saw this on a book a while ago. the icecube can slowly melt and spread in to a pool of water on the floor.

good luck.

i would do it with a combination of softbodies/lattices and particles.

so the melting itself should be easy with blendshapes. if you look at the ice cube melting, you'll see that it isn't the ICE which is goin to the side at the bottom. it's a new surface (the water). this i would do using particles in maya. or wait until you get 4.5 and use the fluids for that.

ok, i haven't used maya in a while, so this may not work, but here's an idea.

1. Eat away at ice cube
a. make a 2nd invisible cube
b. use blend shaped do make it distort
c. use it as an animated booleon object on cube 1 to eat away at cube 1.
d. (this is where i'm not so shure) set up a harbody with the result of the booleon and the floor so it will keep moving towards the floor as it is eaten away by booleon object.

2. Water pool
a. use blobby particles with hardbody collision w/ floor to animate water pool as the cube gets smaller.

i apologize in advance if that is totally implausibe....just sort of brainstorming here
