General Worklflow for fracturing effects

[Johan Forsgren]

Hi list!

We are right in the start of a new project, and we need a fracturing effects, basically an object that fractures into larger chunks, hits the floor and shatters some more. 

Now, I have about zero experience with fracturing effects, We are looking into implosia and momentum but Im not sure, the tests i have made in the past makes me think you have to freeze the fractured geometry before applying dynamics?

Its more memory efficient for sure, but it makes the second fracture once the chunks hits the ground somewhat tricky. How would you go about doing this? 

Thanks

Hi

well you can freeze the fractured geometry before dynamics of course, but if you want something more simple, you can just make the fractured geometry "on live" while simulating, which will allow you to have total control over the kind of multiple fracturations you seem to be looking for, and implosia + momentum can do this pretty easy! 

cheers

latest momentum has dynamic fracturing... it's very powerful (if a little unstable at times)

 

although make sure you allow yourself a few weeks to get up to speed, the manuals leave much to be desired, but there are some good video tuts

Thats good to hear :)  Though I need to show something for the clients by Thursday, so there's not a lot of time to be getting up to speed with anything. In a few weeks this whole project will be over :D 

Is there any documentation on this features by any chance?

Well option is to go fast through couple starting momentum tutorials, catch couple tricks and build something from that. 

Another option is to hire someone that knows how to do that fast for this project and learn for other ones so you keep budget in the house.

I don't think that there is any other option.

But depending on your familiarity with ICE it shouldn't be too hard to create some basic look.

Also there was an tutorial announced recently about shattering ground and I think I saw some shuttering of biger parts into smaller ones as well in there. Maybe that can help..

There it is but I never saw a single tutor from these guys so I can't really tell how good are they.

If Implosia 2 is still in beta try to subscribe to the beta list. I tested it for a short job 2 or 3 weeks ago, and it was furiously fast and stable (compared to the 1.6 version).

[Adam Sale]

agreed. 2.0 is able to generate far higher shatter counts than 1.6, and faster too. 

The texture map based workflow leaves a little to be desired in terms of detail of shatter, but other than that, the rest is pretty rock solid. 

(Please tell me I'm wrong about the texture map based workflow :-)  )
