Fracture organic shape by paint?

Hi.

I'm needing to fracture organic shapes by paint, in Maya.

(5:40 thru 7:00) of http://www.youtube.com/watch?v=7xc3E7Uz3O4

I'd like to duplicate this functionality inside Maya. So that I get fractured pieces of geometry on an organic surface (not just a flat plane). Like here:

Any ideas?


thx

try the voronoi script in creativecrash which can be found HERE

Yeah. I know about the soup voronoi fracture. I'd like to paint my texture directly on my organic mesh shape (not just a flat plane).

More like zbrush painting, then having the texture update the fracture image file but only in inside Maya.

if you want the ability to paint fracture areas on geometry, Fracture FX is great for that:

Thanks cgbiege.

It looks great but I don't see how to paint directly on an organic shape. Looks like I'd have to paint on flat planes.

Maybe I'm wrong.

Unfortunately you are -> with fracture you paint to your geometry the same way as you would paint on a texture > following the UV's.

So it does not matter how "organic" your mesh is.

EDIT:

to be clear:


with FractureFx, you first fracture your whole mesh and then you can mask (by painting) the areas where you want your corresponding fracture-node to affect.

If you need somekind of ability to 3D paint you fracture lines directly into your mesh, then you'll be disappointed ;-)

Not for Maya... But the best so far is RayFire for 3dsMax ........Watch this.

http://rayfirestudios.com

I use both Maya and Max so I can use this and possibly try the new alembic outputs.

This was originally written in Maxscript to use with PhysX. I'm sure someone in Maya can mel or python this to work the same. I'm wishing, .. right?

Thanks ristopuukko.

But yeah, I'm needing to paint directly on the mesh. Fracture does look like it would work in other ways for me though. The goal is however, to paint directly on the object for the most up to date result I need.

I was thinking of a workflow that maybe allowed me to draw curves (or pfx lines), project them into place Then have fracture do its thing.

Thoughts?


RayFire does look cool. Wish it was Maya (Mac)

I'm baffled. Really, I am.

So with fracture you can project your image, drawing,etc. and have your fracturing made from it and that's_not_ the thing you want ?

Ok, so let's say we have a sphere and you draw you fracturing lines into it ( in 3D space of course) but then what?

How is the software supposed to know, how deep inside from the surface will a particular fracture go ?
Through the whole sphere ?
Then you'll be getting the fractures from the other side mixing up your precious fracture design...

What you're describing is a sweet idea but the rules of engagement, well the rules of 3D space, unfortunately makes it more complicated.

Or am I missing something really big here...?
