svetlik Posted July 5, 2023 Share Posted July 5, 2023 Trying to get a Leafy type material using the hair function but can't shape like it shows in the tech manual (Sutton's Dodo bird) using the thickness timeline. Keep getting this octoganal shape instead of a smooth curve (see image). Render is set to multi pass final quality. Any help appreciated.

Hash Fellow robcat2075 Posted July 5, 2023 Hash Fellow Share Posted July 5, 2023 Could you post a sample PRJ with that demonstrated? Quote Link to comment Share on other sites More sharing options...

Hash Fellow robcat2075 Posted July 5, 2023 Hash Fellow Share Posted July 5, 2023 Hi Ed, Although the spline appears to present a continuous controller, it get sampled along the length of the hair by how many "Control Points " are set in the Hair System properties. Set to 3... Set to 7... Set to 11... Higher "Control Points" number will increase rendering time, so set it as low as you can stand. Hairs seen at a distance may not need high settings. However, even with fairly high values, the ends of some hairs may shape oddly (see the two hairs circled in red above). Setting the thickness spline to reach zero earlier than 100% in the timeline helps avoid that. Here I've gone to zero at about the 90% marker...
