blender particles

hi, does anyone ever heard about working python script to convert particle hair, fur etc to renderable mesh? i've just found some outdated (after particle rewrite no more working) which was able to convert them to connected edges (not so usable but good start for modeling).

u'll have to ask smartden to implement such a function within blendigo...if this is possible ofkoz...

there was such a script, though it only made verts/edges no faces, no thickness

indigo cann't render edges

SmartDen: yea, i know.. i just mentioned script ive seen long time ago which was able convert particle hair to edges which i than converted to beveled curves, this used to work a bit but not so practical due time consuming, but this script dont work anymore..

i just wanted to ask if someone knows any script, i've seen some time ago rendered fur in indigo and it was exported from Maya i think.. not sure

In 2.46 there is a button in the particlemodifier to convert to mesh.

really? maybe i should read release notes more carefully

lets see what will happen.. thanks

ok, particle hair rendered in indigo
particles -> converted to edges -> converted to curves -> realigned -> bevel + taper -> export

EDIT:
if someone interested
mesh_edges2curves (Edges not used by a face are converted into polyline(s), bundled in 2.46)
RealignPathAxis.py (Realign path to delete knots)

great

As there already are two scripts... SmartDen, do you think, you could do that automatically within Blendigo? ^^ (If it's not too complicated, that is...)

Wow, thats looks quite good actually.. I like the way the hair tapers down..I may have to have a go at that myself, is it very heavy polygon wise ?

there is default 1000 particles and final mesh has 17000 verts, nothing really huge

That's a very nice "proof of concept" here!

Hi! I´m also playing with the particle system. This is what I got so far (didn´t care much about lighting and materials as you can see):

- create the particles
- editing panel / modifiers tab -> Particles system -> convert
- script window / mesh / edges to curve
- add a BerzierCircle to the scene
- editing panel / TaperOb -> insert BerzierCircle name "CurveCircle"
- raise Bevel Depth and BevelResol
- convert to mesh
- make lighting and materials

But beware: Converting edges to curve takes a lot of time if you raise the amount of the particles. up to 1 / 2 /3000 is ok but the more the longer it takes.
The whole ball (first picture / 30000 particles / only one core active) took me about 5 hours to convert to curves

Woah...those renders are pretty intense. Nice stuff

Is it realistic to use particle to create a carpet for example? Or would that be too long to render?

It depends on how long you are willing to wait
