hi..

 

what we did is kind of fake... we renderedMapped a sequence of the skin, of each charatcer, for each shot, without hair using FG and AO and shadows, (we had a Clone for each character mesh) then applied the rendermap sequeunce to the original

mesh using constant shading, and also transfered this rendermap sequence to the hair.

we set the ambience of the scene pretty high (0.7-0.9)  and  plugged the rendermap sequence to the ambient

port of the geo hair shader, so the hair was mainly ambient lit.. We also added some mixers to change

the tip color and do some variations,,. then we rendered the fur without FG and AO and I think even without shadows..

 

it was almost 2 years ago.. so I dont remember exactly.. I think today it's possible to this in one rendering pass,

using lightmaps... maybe it was even possible back then.. :)

 

anyway you can see the final result here: http://www.ozadi.com/animations/rabbits.zip (14MB QT)

I would go with environment occlusion to get close to FG look.
But I remember Oz Adi on the list use successfully FG with hair, using light map to bake fg effect or something like that...

Volumic shadow map could be the other way but I'm doing some hair rendering like this and I experienced lot of crash ( memory problem I think...).

Before i set off down this road which - to me appears to be madness -  i was wondering if anyone had actually lit hair with FG and got results that were A/ good enough for comercials clients and B/ rendered quicker than hours a frame.

 

Any experiences most welcome before I tie up our renderfarm for weeks...

 

 

cheers.
