Hello, I'm currently experimenting with some hair effects in C4D R19 and I'm trying to re-create a technique that I found in a Maya tutorial. In theory, you create "hair cards" for use in game engines by rendering hair splines and projecting them onto low-poly planes. However, I'm running into a bit of an issue. To generate hair in C4D, you must sprout it up from a surface. Because of that, the roots are attached to that surface and always have a flat, straight look to them. If you take a look at the attached screenshot, the example on the right has hair strands with a nice fray on both ends. With the roots attached to a plane though, I can't seem to find a way to fray the top of my hair (the one on the left).
I have tried messing around with both "Simulate > Hair Edit > Unroot Guides" and the Fixed Roots option in the actual hair's Dynamics tab, but I haven't been able to produce the results I'm looking for. Altering the curves in the kink, frizz, and clump tabs of the material don't seem to effect the roots either. Is there a tried and true method of altering hair roots that I'm missing? Thanks in advance for any advice you can give!
