N!K Posted March 1, 2012 Share Posted March 1, 2012 good afternoon all you houdini gurus out there, I have a 2 part question... I've been using Maya for a few year and I'm making a slow change to Houdini. My first question relates to the particle types in houdini. In Maya there are a few different types of particle render types like point, streak, multipoint, spheres, sprites, cloud, tube...bla bla bla Does Houdini have these, or something similar? I saw spheres, and tubes/capped tubes but don't know if there are others. My second question is...if I were to create a flare, with a bright head and smokey trail in Maya I would use the cloud particle with a expression that would increase the size as the particles age. I know how to do the trails but I can't seem to get a cloudy trail. Maybe a volumetric smokey trail. Do sprites in houdini self-shade? Does anyone have a recommendation of the best way to approach this? Below is my little previz test...and a style frame to which I'd like to match. style frame: http://files.air-attack.com/MIL/ac130/ac130u_20080829.jpg PreViz: Quote Link to comment Share on other sites More sharing options...

N!K Posted March 2, 2012 Author Share Posted March 2, 2012 Thanks for responding. I checked out Peter's tuty but it didn't really answer my question. metaballs are volume? or solid? thanks again Quote Link to comment Share on other sites More sharing options...
sadhu Posted March 2, 2012 Share Posted March 2, 2012 (edited) I don't know if this is the right / efficient way of doing this. Can someone please help us? metaballs_to_volume.hipnc Edited March 2, 2012 by sorry Quote Link to comment Share on other sites More sharing options...
