I assume the reference to fur is a typo
Yes, it was a typo, I've fixed it now.
When I design a NURBS curve and attach a paint effects stroke I can get Maxwell to render it as a hair. I can't figure out how to give the hair 'cone' more than one radius. It's always a cylinder.
Expand the "Pressure Mappings" rollup on the stroke, set pressure map 1 to "width" and use the graph control to set two control points, one for root width and one for tip width. The curve will scale the width set in the brush node. Alternatively, you can set the brush node to create tubes and use the width scale controls in the Tubes rollup.
I spent something like $600 getting Shave 6 for Maya 2012. When the new Maxwell plugin came out I finallt upgraded to Maya 2013 and consequently seem to have lost Shave. There is no Shave for Maya 2013.
Yeah, they're usually pretty slow to catch up to the latest Maya release, I don't know why. They'll release a build with support for 2013 eventually.
