Re: Group of curves to strands?

[Fabricio Chamon]

Late response, but you can merge all curves and use a neat melena compound
that generates strands from a multi-subcurve object

Thanks Juan, no need to dig out the script, I have finished it by now. But I'll
take a look at Dan's compound.
Thx

Ouch...I guess this is never going to be fixed :/
Thanks, I'll take a look at your compounds, but depending on how many curves I
have I will rather do an extrusion script...

Re: Group of curves to strands?

[Leonard Koch]

Yep there is just no convenient way of doing that.
The only possible way is to connect each individual curve into the icetree
and give it its own uv to location node. You can take a look at the curve
data gatherers in LK Fabric to see an example of that.

A rather annoying limitation.

Re: Group of curves to strands?

[Juan Brockhaus]

well, yeah, that's unfortunatly how it is... curves in groups in ICE are
quite annoying... (and guess what, it's not going to change anymore...)

there's a nice compound from Dan Yargici on rray.exe (Create Strands from
Curves) where here basically rebuilds the curves in a group either as
linear or bspline.
that could help, if your curves are all uniform parametrized... and you are
not using mixed curve types...
the compound takes the points and rebuilds the curves. nice little
workaround. but depending on your scenario it might work?

else... well, yes, you have to connect each curve individually
(I've once written a script to help with this. could dig it out. but was
project specific, so may need a bit of rewrite)

cheers,

Juan

Group of curves to strands?

[Thomas Volkmann]

Yo!
I wan't to populate my scene with some cables by laying out some curves. Instead
of extruding them for rendering (you can't render curves directly in Arnold, can
you?) I thought it would be quick and easy to turn them into strands by putting
them into a group and turn this group into strands.
I didn't manage because one or more of the following reasons (tell me which):
 
A: I'm too stupid
B: It's really complicated and A 
C: It's not doable. And A because I even tried.
 
So which one is it? I figured so much that A applies in every case.
If the answer is not C, can someone please give me a hint or two on how to do
it?
In the meantime extruding all these curves by script is simple and fast even for
me, but I really want to know what I got wrong here :/
 
thx,
Thomas
