fuzzy skin

[sliver]

I am trying to go a little beyond simple textured skin. I would like to add the soft fuzzy hair that is present to take it to another level of realism.

I am after a simple technique for emulating a soft fuzz on the surface, if I can emulate individual hairs then even better. Imagine the top of the fore-arm, or the cheek.

I have tried.

1. SaqLite - nope - hairs a far to big and object has to many polygons for this to work.

2. Adding an image map with very fine lines drawn on, taken down to 30% xparent, this kind of works, but up close, looks like lines drawn on the surface. Also no effect on the object edge.

3. Addng a seperate object over the top of the main one, xparent and mapped with the hair texture again. This works ok as I can add different surface characteristics to the hair texture. I am a little worried on doubling the poly count though.

Was wondering if there would be a volumetric technique I could use?

Any ideas, tips, comments very welcome. I will post a few examples once I have some good renders made.

Thanks, Sliver

One way to emulate these is using a fresnel type function. Use this function to make the edges lighter to simulate light coming through the fibres. IFW2 Textures has a velvet shaders and I think the shades project one too.

You might want to check the above URL out. It's not the best solution but you could give it a try. Dave Jerrard also had a tutorial to fake fur but you need to do a search. The other option is to use particle effects (maybe in sprite mode) to emanate from parts of the skin.

Oh, and you have to be a members of renderosity.com to view the tute (free).

Good luck
