View Full Version : Crumbling Object

Greetings. Looking for a way to properly "crumble" an object. That is, if you had an object that was made of clay, concrete, etc. and then it was hit, so that it crumbled into appropriate looking pieces(jagged and irregular)... matching the material it is "made" of... I've tried to do it in explosion FX with no success. I basically want a deformer type process where you would take any object, cube, moutain, .obj... whatever, tell the deformer(a deformer like explosion fx) that it was "made" of a certain type of material, and then based on that it would calculate and correctly generate breakaway pieces.

There's an animation on the maxon site for dynamics under 8.1, which shows a matrix style animation with wall pieces crumbling away after being hit by bullets(?)... but for all I know those breakaway pieces where created one at a time, and then appear as the wall is hit... I'm basically looking for something more automated, yet with the organic and random qualities of something crumbling.

Thanks.
Cheers

Hi,here's a link to the file for the animation done by Michael Welter tht you mentioned.It was done with Thinking Particles.

It's not perfect by any means, but have you explored the shatter deformer?

you could also play with exposion FX just with the settings real low.

alot of the deformers strengths and weakness's lie in the mesh you are using. I.e if you have a regular mesh with all quads andno funny shapes you will have the resulting deformation.

so screw up that model a but before shattering/ exploding it.
