 Hi there,

Do you know if it's possible to duplicate an object X time and reuse each copy as a single object ?

It's difficul to explain, but I'm trying to reproduce in maya some tutorials based on houdini.

I'm trying to do a procedural wall like this  http://vimeo.com/6179556  but in maya and use physx (maya 2012) to break the wall.

Please I need some help and tips :O)

Thanks

Sylvain

It will require quite a bit of work to get something like that going in Maya. I can give you the details if you want, but the short answer is NO. Maya is pretty bad at that stuff right now. I know that developers are aware of it, but don't know when they will be ready to address it.
Plug-ins won't help here. Some core changes are needed. Especially in the shading shading groups engine and supporting attribute functions across all (or most) nodes.
Sorry mate.

Thank you for the explanation :)

PS : Thank Peter for your amazing nodes by the way

Some work has been done with the new MR userdata shader. It allows you to at least use different colors on one shader for your instances.

This kind of stuff is trivial in MTOR and 3DLight for example - in general in the rman renderers. There we have a lot more freedom on the shading/rendering side. Good to see that somebody is trying to address the issue in MR.
But in general MR is pretty bad at this kind of stuff.

Here's a link from the mental images forum discussing userdata and they include some python scripts and examples :)
