hair problem

[Ravager]

i would add my "hair" material to my model and not all of the areas are covered in hair, no matter how much density i put in.

It looks like your normals are inverted. You'll need to flip them outwards so the hair knows which direction to go.

[Stuart Rogers]

I suspect this is a 'normals' problem. Each patch has a front side and a back side. Hairs and other particle systems emit from the front side. Most of your patches are facing outwards, producing hairs. Some patches are facing inwards, which produces ingrowing hairs - the little dots on the bare patches suggests this - they're the roots of the hairs.

 

If you look in the Tools->Options panel you should find an option to "show normals" - turn this on. It might be useful for this to turn hairs/particles off. In the show normals mode you get a single pointy hair in the middle of each patch, pointing out from the patch's front.

 

Select any patches that are facing inwards and flip their normals (in the context menu of the selected group). Once you're happy all your patches face outwards, turn off normals and turn hair back on.

 

Of course I could be wrong about all of this...

[Ilidrake]

Everyone is correct. Flip your normals.

...and reference Exercise 20 in the manual if you aren't already doing that.

thanks guys, it worked! by the way, how do you make the hair flow smoothly with the body instead of it being all stiff, i cant really explain it.
