Hello,
I have a particle system that has the role of debris. I also have 5 objects that represent small fragments. What I'm looking for is a way to instance those 5 objects randomly on to the particle system. Plus on collisions the particles system should react based on the instance shape.
Any help would be great
Thank you,
Adrian

Hi,
I did something like that using RBD Fractured Object. You use the group mask to identify the different debris (which you must have previously grouped in the SOP context) and then you can use the Point Position Node to copy the debris pieces from the RBD Fractured Object onto a particle system. Once that's done you just have to add an RBD Keyframe Active to switch from the particle animation to DOPs simulation and the debris pieces will retain the velocity at the point they were switched and all should become physics simulation from then on.
It takes a bit of figuring-out, but can be done! Like Tony Stark said: once you eliminate the impossible, whatever remains, however improbable, must be the answer"… or was it Sherlock Holmes? They look so much alike!
Cheers

In any case it's a case study! Go for it and ask anything along the way…

circusmonkey thanks for reply, u are absolute right… just for some reason houdini in University's lab does not load the example file from documentation. But I found my the solution here: http://www.sidefx.com/index.php?option=com_forum&Itemid=172&page=viewtopic&t=20941&highlight=instance+geometry [sidefx.com]

of course this possible! But not necessary if you ask me. Debris is usually fast, tiny and with the added motion blur you will never be able to tell if some of the pieces have the same geometry, especially because they're all rotating differently. What I'd do is have like 30 different pieces for the instancing and then stamp different scale values on the pieces, that way you get some variation in size.
