Maya for 3D Printing - Rapid Prototyping
In this course we're going to look at something a little different, creating technically accurate 3D printed parts.

Particle replacing without instancing
Does anyone know how to replace particles with some geometry without instancing. I'd like to have each replaced particle as a separate duplicate of an object which could then have their own dynamic (soft-body) secondary movement. I think this is not possible with Maya's particle instancer.

Sorry, not in front of Maya right now....
Danny in the mel section might have an idea or two for you regarding that.

The problem is that you can only (?) have per particle custom attributes of float type meaning I can't store the name
Any ideas?
*edit*
Maybe I could rename every duplicate to something that includes the particle's Id in it's name but it wouldn't be fool proof...

Here's what I did:
For the per particle creation expression I wrote:
Code:
string $sDupName = ("dup" + particle1Shape.particleId);
string $sNewObj[] = `duplicate nurbsSphere1`;
rename $sNewObj[0] $sDupName;
Code:
string $sDupName = ("dup" + particle1Shape.particleId);
if(particle1Shape.age >= particle1Shape.lifespan)
delete $sDupName;
else
{
vector $vPos = particle1Shape.position;
setAttr ($sDupName + ".tx") ($vPos.x);
setAttr ($sDupName + ".ty") ($vPos.y);
setAttr ($sDupName + ".tz") ($vPos.z);
}
Code:
if(frame == 0)
{
if(`objExists "dup*"`)
delete "dup*";
}

particleShape1.scalePP = rand(.08,.4);
particleShape1.rotPP = rand(0,360);
string $sDupName = ("dup" + particleShape1.particleId);
string $sNewObj[] = `duplicate target_plane`;
rename $sNewObj[0] $sDupName;
Thanks.
figured it out. I should stop posting, because half the time I figure it out before people get a chance to reply.
