View Full Version : Shattering Glass using Hard Body Dynamics

Attached is a image I've just completed for the cover of a brochure. When you open the brochure, the first page shows the same image, but with the glass broken and the brochure missing. The whole job is only two colour, so this image was rendered and then I created a dcs file in photoshop.

Anyway, tonight I have to model the glass as being broken and show some small pieces of glass inside the case where the brochure was.

I was going to model this the "old fashion" way, but thought that utilising hard body dynamics would be a nice llittle experiment.

I have never used this feature before, so was wondering if anyone out there has any tips and tricks to help keep a novice on the straight and narrow.

I tried my hand at dynamics yesterday and failed miserably, so went ahead and modelled the glass manually. Will try again later when I have more time, but would still like to know of any tips or tricks anyone may have.

Have you tried any of the plug ins meant for breaking objects, like C4?

I thought I would try the built in features first before splashing out the dosh.

Thanks anyway Silk. I had a search on Flay and C4 looks pretty cool, but it looks like the same old problem of a plug-in being for PC and I'm on a Mac.

i always found kaboom to be really good for this sort of thing.
it's free and even has a tutorial on breaking glass too.

if you give up on HBD then you might try it out.

problem with using dynamics is that you'd have to split your model up into lots of little pieces, it won't 'smash' the glass for you.

so if you want to use dynamics for a realistic glass break, with shards, jagged edges etc. you still need to model them yourself anyway!

It seems that whatever you use, you have to model the geometry to shatter.

I had a look at the kaboom tutorial, and that had a cool way of breaking up an object starting with a point cloud.
