hatrick Posted August 9, 2010 Share Posted August 9, 2010 hi, Is it possible to control hairgrowth with a ramp ore something for a dynmaic growth animation. For example the growth should happen along TX with a smooth falloff. I played with groupingstuff and thought about popattributes but i did not get closer so far. A little hint would be great. thx HT Quote Link to comment Share on other sites More sharing options...
Macha Posted August 10, 2010 Share Posted August 10, 2010 Have you tried adding a furlength attribute in the skin node of the fur? That allows you to treat length like an attribute. Quote Link to comment Share on other sites More sharing options...
hatrick Posted August 10, 2010 Author Share Posted August 10, 2010 nice macha .... the ramp was only a thought and i'm not shure if it's the ideal solution... could you imagine a solution with particles for a more dynamic setup ? greets Lucas Quote Link to comment Share on other sites More sharing options...
Macha Posted August 10, 2010 Share Posted August 10, 2010 Maybe, but I'm not sure what exactly you're after. What kind of behaviour do you want the hair growth to have? Quote Link to comment Share on other sites More sharing options...

What kind of behaviour do you want the hair growth to have? pls see the image attached .... the growth should appear like a wave over time in oe ore more directions ... greets Edited August 10, 2010 by hatrick Quote Link to comment Share on other sites More sharing options...
hatrick Posted August 10, 2010 Author Share Posted August 10, 2010 (edited) pls see the image attached .... the growth should appear like a wave over time in oe ore more directions ... greets and by the way .... what local variable do you use with the chramp ex. ? EDIT:news here .... i ve found the $BBX a.s.o. variable verusefull here although a pop solution would be very interesting thx !

Macha Posted August 10, 2010 Share Posted August 10, 2010 How about these 2 methods? fur.hipnc Quote Link to comment Share on other sites More sharing options...
hatrick Posted August 11, 2010 Author Share Posted August 11, 2010 (edited) How about these 2 methods? thx a lot for your time ... interesting examples... i'm happy with the chramp-solution with the boudingboxvariables in terms of growth dynamic, but now there is another problem... how to zero out hairs with more than 1 segment... when you look at your example there is the same problem... i thought about resamling afterwards but i d like to use the nice controls of the fur SOP.... further tips would be great thx Lucas Edited August 11, 2010 by hatrick Quote Link to comment Share on other sites More sharing options...

Macha Posted August 11, 2010 Share Posted August 11, 2010 (edited) I think this is due to an attribute called furfrizz. Just do the same for that attribute as you do for furlength and that should solve it. Btw, there is also an lengthmap option on the Appearance tab.
