help with shag hair

[yair]

shag defualt render is to shag render which is fast but sucks at antialising as well as shadows and such. try enabling geometry.
the render takes much more time but itll give you what you want, i hope its not allready turned on...

oh ye.. very nice model, texture and hair
good luck

I see your point, and I myself have the same problem, shag hair is a good tool. If you do want to learn the further details, I'd like to show you a picture , and hope it will give you a hand. Since the picture is too large, it will not be clearly shown here. You may click the follows : http://www.chinadv.com/bbs/show_image.asp?image_name=photo/2001127332344323.JPG

Good luck!

It looks to me like your scene scale is screwed up. It sounds odd and it probably shouldn't make any difference, but your scene scale has a big effect on the quality of the render.

Other things to try:

Turn up the memory/quality setting a bit (to something like 9) in the ShagRender rollout, make sure you have hair enabled lights in your scene, turn on Shade Spline Segments and Shade Bezier Segments in the ShagHair rollout.

There is absolutely no reason to enable geometry hair unless you are a) using a renderer which doesn't support Shag as an environmental effect, or b) you need GI on hair. If you can't get the hair to look right as an environmental effect then you are doing something wrong, simple as that.

Well, thanks for all the suggestions guys.

Yair I tried to enable geometry and it actually went faster than I thought (around 4 mn instead of 1.5 mn). The result was also much better than what I had. I'll post some new pics after I make some adjustments if anyone is interested.

Iain, what do you mean with scene scale being screwed up. The whole character is 1m60, and the scene units is centimeters. It usually works fine. everything is in order regarding lights and memory settings. I wanted to avoid turning on shade segments, because render times just go through the roof ( 20 mn for just the head ) and I still have artifacts of some kinds.
But I agree with you, I probably did something wrong, because it's the first time I've had such a bad looking shag hair.

Forget-me-not I'm not sure I see what you're trying to point out. I've seen the completed picture on raph.com and this is truly awesome work. But can you be more explicit with what you're trying to show with the viewport captures ?

The picture I showed you is my friend's works, I know the whole process how he did it.
He used 12 id totally, to control the hair part, also with shaghair. I learned from this works that the most needed thing when using shaghair was PATIENCE. He adjusted the hair for exactly one month. The reason why I showed you this picture is to let you observe the hair in details. Hope you do better.

You might be able to check if it's a scaling problem by allpying the reset Xform utility to your mesh, it would only take a minute so it's worth a try.
