well, i got a response from pixho himself (emmanuel)... anyways, he says the velvet shader is out of date and needs some work, which he's actualyl going to do! love that guy.

anyways, i'm trying to find another way to achieve that effect. Anyone know a good script/plugin/shader that achieves this kind of effect in the picture above? (i'm sure you can all picture how its supposed to look.

Hi,

I agree the velvet_hs script is really a pain to manage, so I made another one for a personal project (which will be online very soon).
The shading network allows the user to control the color per pixel according the light orientation / intensity (see example).
It works with any kind of material as it affects only the color (so the specular remain the same according the kind of material you use)

It also works great for human skin (I made some tests with and it looks great so far)

I hope to release it soon...

Hi all,

well, I invite you to see on pixho an animation 'waiting for Auriane' announcing a very important event to me.
It shows the velvet shader in 'action', (yet not available to download, but very soon)

I suggest you see the divX anim (PAL res and high quality)

Thanks and enjoy!!

I'll be glad to discuss with you if you have some questions


Ciao

news tab (on the left index page)

Follow the link 'waiting for auriane' to the Auriane main page.
Maybe make a reload for your browser (in case the page is cached)

hee that's lovely. I especially like the butterfly,oh and the velvet shader of course!

on my computer the divx freezes near the end.

Could you tell us a bit about the new velvet shader: is it just boosting the illumination on the lit side of the object where the facing ratio approaches 90 degrees?

well, the velvet reacts according the normal camera but only with the light incidence.
You can use the network to saturate/desaturate the color of a texture, or drive a ramp to control exactly the colors of a material with a ramp.

All the clothes of the little characters are made this way and it gives a very smooth render.
