Using Pfxhair To Stop Stroke Twisting

[tallhonkey]

I read an earlier post about pfx twisting and followed the post to a blog on Duncan's forum that seemed to offer a solution. One thing I noticed when I tried to implement the method was that my pfxHair tube/ribbon did not closely follow the original curve in the way that the pfxStroke did. In the follwing image you can see my pfxHair tube on the left and a standard pfxStroke on the right.

The pfxHair tube seems to closely follow the CV's of the curve but not the curve itself. Then, when you turn up the subsegments (in my image subsegments are set to 10), the tube just subdivides the area bewteen the CV's and doesn't make the tube follow the curve any more closely.

I'm sure there is a simple solution but I can't see it.

In the options for "make curves dynamic" turn off "exact shape match". The "make curves dynamic" by default uses the curve hull so that output curves exactly match. In other words it simulates using the curve cvs instead of sampled points along the curve. The subSegments on the hair system use a hermite smoothing of the base simulated hair. You may wish to increase the follicle sample density instead of the subSegments to more accurately sample the original curve. This would mean more simulating segments, but you are probably not simulating anyways, so increasing sample density is better than subSegments.

Thanks Duncan,

That's great I'll look into that. Our job is finished now and we had good success with Maya Hair.

Really looking forward to what's new in Maya 9!
