Hair thickness / rendering

[timo-s]

Can somebody tell me what Hair Thickness depends on? (XSI Unit or pixels?!) How do I know how thick a hair should be? Is the distance between the camera and the Hair important?

And is the scale of the geometry important! For example how big should I scale a human head and how thick should the hair be?
Or is it all a good guess

And when I apply the Hair_Renderer Shader to the Geometry Hair I only get black shading.

hi there!

im new to softimage and i also got questions about hair, so...

i tried to test hair on a simple sphere and one spot light.
the result wasnt that good, so i checked the forum for hair topics. there were a few, but they all say that hair is buggie and we should wait till the next release of xsi. is this true?

another thing: how to manage the hair renderer in the render tree?

can anybody give me a short step by step description of the correct hair procedure?

thx in advance! cya
