Re: disintegrating sand

We have a similar problem to solve.  At the moment, we're doing some tests with Syflex to perform the "melting" phase of things, with particles being emitted from the surface.  We're getting some cool results from this method.  

The only thing with Blastcode is that it only works on NURBS models I believe.  If that's not an issue, it's a really powerful tool to incorporate.

There is a plug-in for Maya, Blastcode http://www.blastcode.com/

You may have luck using that (or something alike for XSI) to generate
chunks of the sandcastle breaking off, then take those chunks, smooth
and/or relax them while they´re emitting themselves into particleblobs
and have those dissolve into extinction?

Never used blastcode sofar...
