BroadStu is working on a strand rendering for Cycles...
Hi all! I have recently been working on a patch for strand rendering in cycles. It's still very early and is currently on the tracker to be reviewed by Blender's developers. It can be found here.
There are also a few more implementation details there. Currently, there are plenty of missing features and I wouldn't recommend heavy usage now. It's currently quite memory hungry. This thread is primarily for suggestions, debugging and tests.
It's not had a detailed review yet but if anyone wants to support me or donate to this project then just see my profile or get in touch.
