birth script with particleShape issue

#1

Hi,

I’m using a birth script to copy position and shape of en existing model.

I did this before and worked fine, but this time I get a problem… my model is not made of simple shapes, but of groups and it seems like it gives an issue to my scene.

I keep getting this error when calling the array containing the groups:

MouseTool:ScriptActionF649CE0
– Error occurred in i loop
– Frame:
– i: 1
– called in Proceed()
– Frame:
– pCont: ReferenceTarget:MaxscriptParticleContainer
– t1: -160.0

any help?

Thank you

Hal.

Hard to say if you don’t post the actual script. It could be something as mundane as forgotten parentheses, or something more complex…

nooch…thank you for reminding me of how distracted I can be :smiley:

here is the code:

on ChannelsUsed pCont do
(
pCont.useAge = true
pCont.useTM = true
pCont.useShape = true
)

on Init pCont do
(

GLOBAL Vetro = $Lego* as array

)

on Proceed pCont do
(
t1 = pCont.getTimeStart() as float

 if (t1 < 0) do
     for i = 1 to Vetro.count do
         (
             pcont.addparticle()
             pcont.particleindex = pcont.numparticles()
             pcont.particleAge = 0
             pcont.particleTM = Vetro[i].transform
             pcont.particleShape = Vetro[i].mesh
         )

)

on Release pCont do
(

)

If “$Lego*” is a group you will need to collapse the group objects into a eMesh or ePoly in order for it to work. You can work with objects within a group but not on groups themselves, not within a script, at least to my knowledge.

Someone may know of a workaround for this but it isn’t me :slight_smile:

indeed JohnnyRandom, but I hoped I could do it in a script…I have 804 groups.

now that everything is been converted the script works.

Thanks for the support

Hal.

quick reminder…how fo I transfer the original material from the mesh to the particles?

I have 6 different materials and would love the particles to pick them up when getting shape and position…

Thanks.

You would need to use a sub-object material and assign material IDs in the script. Attached an example, notice the Material indexes assigned to the materials themselves in the multi/sub-object match the corresponding material IDs assigned with the Materiel Modifier.

thanks JohnnyRandom.
