Why useless? I can export particles from 3ds max and they render out fine most of the time

what do they render as?
im just reacting to people being like 'i wish you could export this and that' to things that right now dont have a counterpart in Indigo is all. its like trying to translate a word that doesnt exist in another language.

you can export particles as meshs...
That may work in some situations, but definately not in every one.

Fur/Hair may come out quite nice

What they should be then? Not meshes? Aren't they always meshes? Even a single sided particle is a mesh

That was meant as answer for StompinTom

what do you render as?

theres already support for dupliverts then. i havent caught up on all the new features in 2.44, but is it possible to convert particle hairs into meshes yet?

yes, someone found an linked a phyton-script for that...
Don't ask me, who, or where you can find that script.

an example:

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)

here's how to run it - select your particale system and...

I did this back with 0.6 and it took forever to load+render. I gave up.

maybe, you should rerender it with 0.8 and SSS

i know that script, but what you get is single line of joined verts, does indigo render this kind of object? or did you something that we don't know???

i may have extruded those lines into (very very narrow) planes or boxes as well

as i thought

but this is bad for sss, etc, everything where normals are important
