Hi Reinhard
Even if your pictures are tests they are looking really good!
I didn't had time to try Matheus compounds, but I know that actually segments size are in screen space?
Do you have any idea on how to deal with this and camera animations?
I know you can link it with camera distance, but it a trick and there's also the focal !

Thanks! Yes why mental is using pixels for strand units I don't quite get either, probably needs fixing . I don't know any way either around this except the workarounds you mentioned.
Also what needs fixing that hair lit from the side hardly casts any shadows (The hair segment billboards stay oriented to the camera, not to the light when tracing the shadow)
..and that rasterizer bug that attributes sometimes get garbled with >10000 strands :o3
Cheers for putting the picture in the gallery Hirazi!

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!

edit: Oh, quoting images doesn't work; I'm talking about the curly short black hair

Moderator edit: go to the image properties, copy the image url & place it inbetween [img] tags... - HB

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 :ymblushing: ) 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!
