Akabane Posted July 19, 2009 Share Posted July 19, 2009 (edited) Hi everyone, just downloaded Houdini Apprentice and i'm thinking of using it for what the dynamics/sim/particle stuff is concerned (i'm a Maya guy) I was just toying around with some of the powertools houdini has to offer. I really like the procedural node based workflow, it's great. I'm just a few hours on it and already feel (half)comfortable with that way of thinking And, well, as lots of people switching to houdini (i think lol), the first think i tried to do is DESTROOOOOOOY things! Well, no more useless speech, let's dig into my questions! I'm trying to add debris to my RBD Glue Objects. Well, actually i made it. But one thing that's dooming me is which metod is best for instancing: Instance, or copy node? What are the benefits/downsides of both methods? Because i feel i'm getting the same result, but i don't know if i should use one or another! Second: i want a SECOND pass of debris coming from my object (say, one for instanced mini pieces of geometry, another for "point" particle to represent fine dust or something like that). But if i try to do that, nothing happens. Should i simply copy&paste the nodes inside my debris node, and create relative nodes into the Dop network? Or is there a better method? (i fear i can do some damage doing that ) Theeeeen...just a question as it is (i didn't try to be honest, but since i'm here, why don't ask!). If i want a "cloud" of smoke/dust coming from the shatter with fluids (see attached mov) how can i say "hey, well, at frame 10 you can start the sim"? I repeat, didn't try atm, so you can bypass on this one and i'll just discover it myself (or i could just export the baked geometry in maya and composite that XDD - oh wait. I'm on apprentice, cannot do that.) Attached is my first simple simulation in my new flashy Houdini Apprentice! It gives satisfaction Thanks you all, awesome community sbum.mov Edited July 19, 2009 by Akabane Quote Link to comment Share on other sites More sharing options...

If you run into problems, use MantraInstancing. I suck at DOPs so I'll stop here. Quote Link to comment Share on other sites More sharing options...
