evanrudefx Posted June 7, 2017 Share Posted June 7, 2017 Hi all, I have a question about simulating hair in Houdini. In maya, they have settings that can be mapped to the different positions along the hair strand. You control it via a ramp. For instance, stiffness curve. You can adjust the ramp so that the root is stiff, but the end tips of the hair is loose. Is there a way of controlling attributes like this in houdini? I want the roots to be stiff and only the tips to be loose. Thanks Quote Link to comment Share on other sites More sharing options...
adrianr Posted June 7, 2017 Share Posted June 7, 2017 http://www.sidefx.com/docs/houdini/nodes/dop/wireobject Looks like kangular is the one you want, vertex attribute. Set this as an attribute on your curves in sops before it goes into dops. Drop down a uvtexture sop set to rows and columns to get uv cordinates for your curve, then put this in a vertex wrangle to set kangular based off those coordinates fed through a ramp. f@kangular = chramp('kangular', @uv.x); This value will be multiplied by whatever you have kangular set on your wire object so probably easiest to keep between 0-1 and just dial up and down in dops for your look. Just be sure to hit the little slider+ button to make the ramp or everything will be 0. 1 Quote Link to comment Share on other sites More sharing options...
