Hi all, how would you do hair in blender-indigo? Quite realistic?

I was thinking about manu subsurfed planes ( something like nurbus surface) with hair texture, prepared like grass in grass tutorial, any ideas how to do this texture, because i have done only one god texture, i'm noob in this.

Maybe i shoud drawn it on my own?

I don't think it's the best way.. too difficult

Maybe I should use blender 2.46 RC with the hair tool

Here you can find video presenting this new tool. For the mat, I should use a blended from diffuse or phong to null, using a blend map. I don't know how these particuls works exactly, don't know if it works with indigo

But particles, does't work with Indigo, right?

Yes but you can convert particul in mesh, with "alt c", don't realy know if it works, I just supposed it will

Some members created hairs, search forum

the problem with that conversion is, that you only get vertices or edges, no faces. you'll need to take the whole mesh and extrude it a bit, so that you get volume-hair...

I gets only verticles, no edges...

oh well......
then, you have to do even more work...

Code: Select all

# Converts particles into a mesh with edges for strands
from Blender import Scene, Mathutils, Effect, Mesh, Object
scn= Scene.GetCurrent()
ob= scn.getActiveObject()
me= Mesh.New()
     
effects= Effect.Get()
for eff in effects:
    for p in eff.getParticlesLoc():
        # p is either a vector or a list of vectors. me.verts.extend() will deal with either
        print p
        me.verts.extend(p)
     
        if type(p)==list: # Are we a strand or a pair, then add edges.
            if len(p)>1:
                edges= [(i, i+1) for i in range(len(me.verts)-len(p), len(me.verts)-1)]
                me.edges.extend( edges )
     
print len(me.verts)
ob= Object.New('Mesh')
ob.link(me)
scn.link(ob)

try this python script... it should convert particle-hair to edges....
though, I've no idea, whether it works with the new particle system...
