These looks really great!
I was wondering, Anto, if it would be possible for you to make a nice video tutor or something to get us fast into process?
Being a bit low with time it is hard to get into more details but I would love to check this hair more. I've downloaded some version a while ago and never get a chance to play with it really. Some video tutorial that can put us into speed with tool would be really fantastic. I know it is a lot and take a lot of time but..
I would love to implement that hair in my projects and spread it around but it is hard to start learning and testing something in the middle of project with deadline
)
Keep up the great work and I really hope that we will see more of your hair around. Well not YOUR but.. you know what I mean
)))

Hi there,
As you probably noticed, images in this gallery were created by RRay, not be me
I added only one...
The first on my todo list, is to finish
Node Reference that RRay already started - especially I would like to add a few explanations about nodes. Also, small updates to existing
tutorial. Then I planning to play with Eric Mootz's plugins that I already bought, but didn't had a time for them
Now seriously, I hope there will be another tutorials.
Cheers

Working on a more diffuse hairline. This is still much too dense

Hey rray, can you please share more information about linking the strand size to camera distance? How to go about that? The hair I have looks great until I pull the camera back, then it gets thicker. Thanks!

That one looks really nice!

Thanks Steven, I will continue the spamming^^
izze, I've never done this but try something like this.
The hair will have to get thinner when it's further away from the camera. There's usually a ^2 somewhere in the equation when it comes to distance/size relationship but I don't know the exact math.
I would try 1/(ctr_dist_cam(emitter_nurbs)^2) as a factor for the hair thickness.
Also if you intend to modify the camera's fov, I would work this in as a factor as well.
So unless there's something fundementally wrong with my maths here (probably is
) you would set something like 1/(ctr_dist_cam(emitter_nurbs)^2) * (1/Camera.camera.fov) * 5 as the expression for "size" in kH_Emit_Guides (try different values for the "5" depending on the hair thickness you want)
miga, thanks!

Btw: I just read on the Softimage mailing list, the pixel size unit thing was changed in 2011.
What will (all of) the consequences of that change be? From this thread I understand at the moment there's a problem when rendering animations with K-hair (the hair thickness doesn't stay constant relative to world space), right? Is it a MR issue or something else?

It's Softimage issue, that can be fixed by adding a few nodes. Consequence is that hairs looks thinner with camera zoom and reverse, also, render region and final render can look different...
For animations, without some wild camera movements, I found the current option a bit better, to be honest. Seems to be much easier to get correct anti aliasing...
