Rendering Yeti

[bazuka]

Hi guys,

is there a way to render yeti as a ribbon? mtoa has an option to change the way you wanna render it but i cant find it inside vray?!

any solutions?

what is a ribbon exactly? I've looked at their doc but its unclear.

Dmitry my friend

the way you wanna render the hair (curves), i think vray has an option to render yeti only as a cylinder, on the other side in mtoa u have options to render as ribbon or ticks:

Ribbon
Ribbon mode is recommended for fine geometry such as realistic hair, fur or fields of grass. These curves are rendered as camera-facing flat ribbons. For secondary and shadow rays, they face the incoming ray direction. This mode doesn't look so good for very wide hairs or dramatic zoom-ins because of the flat appearance. This mode works best with a proper hair shader (perhaps based on a Kay-Kajiya or Marschner specular model).

Thick
Thick mode resembles spaghetti. It has a circular cross section, and a normal vector that varies across the width of the hair. Thick hairs look great when zoomed in, and are specially useful for effects work, but their varying normals make them more difficult to antialias when they are small. You can use any shader with this rendering mode, including lambert, phong, etc.

You can try and disable embree for hair (settings tab > system > use embree for hair) and use a vray hair material - it should render the strands of hair as flat surfaces. VRayMtl on the other hand will always render it as a cylinder and adding embree acceleration for hair will always render cylindrical strands with rounded tops and added segments. See if that works, other than that I can't think of an option in vray that does that.
