Hi,

On the Autodesk The Area I saw a demo of an ICE compound fracturing an object. Are there more tutorials on this -> with gravity and rigid body collisions.
I know there's something like StudioNEST Kratos. Has anyone more experience with this feature? ( I think that's something we are missing and that makes me still look a Sidefx Houdini otherwise
Softimage would be almost the PERFECT 3D content creation package for me.)


These guys are planning to do a version of their software for Softimage

For rbd you got either builtin physx or momentum 2 (which, in my opinion is much more stable than physx)
For voronoi fracturing - free Kratos
2012 will have ice modelling tools so maybe we we see more tools for (interactive) demolition.

I must say that latest built of Rayfire got some serious speed improvements (there is also volumebreaker and PDI for max)

From what I read there, they're aren't planning a version, but they're (seriously) considering it, which sadly isn't exactly the same.

BTW - Waiting for Softimage to catch-up with Houdini could mean a long wait. And although it might seems that this is the path Softimage has chosen, personally I wouldn't necessarily welcome it...

I still feel SI is lacking a bit in the demolition/fracturing side considering competition.

I wouldn't like to start a new post for a question of mine very relative to this post: Can we in SI or even using momentum somewhow glue the pieces together so they don't all fall appart when they are not Sleeping. I see this exist in almost all other Fracturing and/or Simulation solutions. And it's not that I just want a feature, it's possible one of the most convenient ones for such tasks.

I'm pretty sure this is a default option in Momentum? But even if it isn't - since everything is exposed in ICE, you get a ridiculous amount of control over just about everything.

No I don't think momentum works this way, or at least I haven't seen any simulation like this online. I consider this a very "default" behabiour to have for me to get into ICE for it.

Um, maybe we're talking about different things? Momentum 3 has dynamic fracturing, the object stays in one piece until it breaks.

Yeah. Probably we are talking about something different. What I'm talking about is on the simulation rather than the fracturing part. The different clusters are kept "glued" untill they receive a specified force before they break apart.

Oh, there are a ton of ways to do this in Momentum. For example here, timecode 3:05

Or here, timecode 10:45:

Thanks.. Yes I've seen those videos and the parts regarding clustering but had my doubts.

So lets say we have a fractured wall and we want to create just a whole in it because a random object is passing through it. (the typical example). Of course we don't want all the pieces start falling apart, but rather only the ones that enough impulse is applied to them by that random object or by the rest of the chunks.

We would go about it by putting the whole wall into a cluster and then releasing chunks based on the impulse that is applied to them. I don't have momentum, so I don't know if thats how it goes or similar.

For such a simple scene I know that it could be done manually, meaning that i could just select the pieces I want and make them rigid bodies, but for a more complex scene (house) it's impossible.
