I am wanting to create textures based on a hair particle system.
The answer to this question says
There are 2 techniques. One giving the best results but being rather complicated and very computationally expensive (involving converting the hair to mesh, UV mapping the hair strands in a particular way and baking particle color in another complicate way and then baking the whole thing)
That's all they say about the first option, they then go on to explain a second option which I tried, but was not happy with the result. I would also like to bake a normal map, which is not possible using that technique.
What are the details of the first technique?
