occlusion for maya fur

[lazzhar]

I assume you mean and ambient occusion pass but I wonder you really need it? For nice contact shadows I'd just get rid of the Fur or model something that has the overall shape of my furry model then render an AO pass for that.

Sorry if this doesnt help too much.

cant remember where i download this pic.hope that the author do not mind.

any idea (beside ambient occlusion pass),how to render other passes and wat are those function?

[lazzhar]

Interesting how they rendered the AO on the fur.
According to the picture you posted it's by La Maison http://www.alamaison.fr/
Maybe they devoplped something special to render that.

Isn't that from commercial done with XSI & Shave and a Haircut ? Maybe ask at XSIBase ?

Edit: hehe lazzhar was faster :D

[ybleong10]

that mean it is done by shave & haircut. is that possible to do it with maya fur + mr?...:sad:

It almost looks like the fur is shaded by the surface underneath.

You pipe the luminance from the solid surface underneath to the fur luma.....

exactly how they've done it..as simple as that.(know it from a friend who worked there).

They simply baked the occlusion of the model on a pass and apply it to the color of the fur..:)

it works !!!

cheers

It works. I just pluged an ambient occlusion shader into the base color of the Maya Fur and it renders the AO without any problem.

Nice inputs about rendering FURs

cool technique!!! i must try it now....

Just read in cinefex that to create the wookie fur, AO maps were calculated and then baked.

And that is all I know!

Shave and a Haircut in XSI (which is XSI fur) has a lot of features that Shave and a Haircut for Maya does not, with one of the main features being transparency of the hairs (in Mental Ray I mean. The Shave render buffer has transparency, but it's not as cool looking as the Mental Ray renders).

In XSI, you can have a transparency value on both root and tip which will blend from one value to another. This is currently not possible with Shave for Maya (rendering with Mental Ray).

The last I heard from Joe Alter on his Yahoo Group was that the values needed to make the transparency work in Mental Ray are all there, someone just needs to tweak the code to make it happen (most likely meaning that Joe knows about it, but he hasn't implimented it yet).

Maybe if enough users request it, the feature will be added sooner rather than later. I know I would get a lot of use out of it.

Speaking from experience, transparency in CG hair makes a HUGE difference in being able to hit soft looks faster.
