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!

Btw: I just read on the Softimage mailing list, the pixel size unit thing was changed in 2011.
