hi,
im working on a shot of a man jumping off a cliff. the animation was done with maya 4.5 and eventually will be composited to the background plates shot in S16mm(part of a short film). im done with the animation and im facing now the difficult process of texturing/shading. i shot some stills of the actual actor who suposedly jumps(chest, back, legs, hands), but i cant find a way to make it look believable. the best way so far is using a layered shader consisting of a lambert and two blinn shaders, twiking their values and colour mapping the pictures, but im probably in the wrong direction. also i need to add hair in the chest and head, but for some reason when i apply new fur i only get in some parts of the body. i know its not a uv problem, the modelling was done correctly(i didnt do it).My model is polygonal and too heavy to be converted to nurbs, so how can i paint some of the hair(instead of using fur).
any ideas?
thanks

Yikes, ok.

Skin is always a hard challenge, I'm not sure if I can help with that. If it's a body double type animation, I'd say use as much texture from photos of the actor as you can.

For the chest hair though, what if you created like a 'proxy chest plate' out of NURBS geometry. You could apply the fur to that and then set the 'plate' to be non renderable. Depending on how much his chest deforms, you may only need to parent the 'plate' to one of the spine joints. Or if it needs to deform, you could either smooth bind it or use a Wrap deformer to attach it.

But do you really need actual hair? Or could you just apply it to the chest texture instead?

I guess it all depends on how close up the shot is and how long you see him for. If he's jumping off a cliff I suppose you won't see him long, unless the camera follows him down or something...

I could very easily paint the texture of his chest/legs instead of going with fur, only I'm using the same placement for the whole body eg. using the same shaders and just map a picture in either colour or difuse values and that is only because i dont know how to map different pictures to the same object without having to unwrap the uvs(which i definately dont know)... it is a steady long shot, so going for fur is not worth it, but what else can i do?

You might want to follow this thread:

All about skin (it's huge)

A man jumping off the cliff? Hair? Please don't make the mistake of doing a whole lot of work that we'll never see. If it's a long/handheld/motionblurred shot, then the kind of detail chest hair gives just won't help.

For head hair...fur or pfx on a nurbs proxy as Jozvex suggested.
