Default Crack

Can anyone help me how to create a crack on a polygon object. I have animation of a snowball hitting ice,...and would like a crack to appear from where the snowball hits.


Thanks in advance

Shameless plug: http://elephantanimations.com/crackterrain.html

That's the best way I know of doing it and it gives you lots of control and flexibility.

I did this before using Blastcode plugin trial version, But it somehow broke and the cracks dissapeared. Wondered if there was a better way.

my fault in the description i only put 'crack'


thanks

It's fairly dependant on how much detail you want to have, as imho any method that involves bolean operations gives you completly the opposite of control and flexibility. Boolean ops are very unstable in maya and anything more complex than the demo in elephantinc's video will likely not work in maya.

Another possible option is downloading a freebie shatter tool (pulldownit, etc) & Rigid Body Dynamics plugin (bullet, etc), as maya's is pants.

Or possibly, using an nCloth tearable surface as the surface of the ice.

cheers,
Chris

Should do, or you could also have it as one thing, instead of having a line shaped thing, model it in to the shape that all the cracks make together (which you can do since they start from a centre point)
