fur uses the uv's to distribute itself. Do an automap on a duplicated uv set and apply the uvs to the fur node. Or just do auto map on your base uv set.

You probably want to fully learn about UVmapping before proceeding with advanced modules like fur

Heres a good tutorial.

hey thanks soo much will look at that when i finish work :P well at the moment i just wann know how to unwrap my uv's into a map so then i can take my model into mudbox so i can poly paint and add details for mapping then i'll learn the complicated stuff such as fur, once again thanks for the link this will help A LOT

Before you unwrap, you might want to make sure the mesh is evened out a bit. Looks like you've got some vertical lines too close together going up the back of the head, and I'd also have a go at cutting down on some of the geometry in the shoulders (pretty heavy compared to the body). Evening out it best done without smooth-preview on.

Theres one major reason, seams. It's really difficult to texture when its split that way (try painting a pattern that covers its body and you will see what I mean). If you are painting textures with a 3D app (like mayas 3d paint tool, or zbrush / mudbox / bodypain / whatever) then its not as much a problem, but you should really learn how to do it properly.

eeek...just typed an essay and lost it! OK will start again ;-)

In simple terms having control over your own unwrapping also means you can stretch the areas of high texture detail to fill much of your grid and shrink the rest. Also you can chose to select the head (for example) and unwrap those UV's in a way which means your characters whole face is spread out in one mesh in front of you so you can texture fine detail on the face without seams through the cheek or somewhere. Remember also that you want your geo to be as close to finished as possible as changing geo later will require remapping some of the UV's. Finally good UV's are useful before binding and deformation later, plus as mentioned for even fur distribution etc.

I have used RoadKill and other auto unwrapping tools in the past but have to say doing it manually has become so insitinctive now it doesn't take that long and I kind of get into a headspace where I find it quite relaxing now!

Painting weights however is another story! :x

Those big gaps in your automatic layout could lose you the job. The company can only fit so much gama data on their CD and currenty less than 1/3 of your UV area is actually covered by paintable mesh. Unless you make islands bigger, they are only taking a small fraction of the painted UV space and when blown up large on the final render, the textures from those mapped-too-small areas becomes pixelated.
Followig what Laz said, look at how the arms were automatically laid out... front and back views. Now, if you manually cut the map, the arm is a long tube, and only needs one lengthwise cut to lay out flat. This also means one less of those seams Laz mentioned. (Seams are bad... especially where two meeting hand-painted islands end up having a visible line of texture difference).

no surprise i need help again with displacement mapping it's just not working i must be missing something or not doing it right, i was following this tutorial http://www.youtube.com/watch?v=dOrmlnIZrAM but it comes up with just a normal smooth render or the eyes and lips inflate like a bad face lift job

i've up load a zip file containing my project if someone could tell me where i'm going wrong that would be great and much appreciated...... oh and if you take a look and think the model is HUGE i imported the mesh back from mudbox
