[Closed] material on particles

How do i script the material on the particles

I give it a shape but it doesn’t copy the shape material

birthscript:

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

on Init pCont do
(
	global Meshes = $Box_Parts* as array
)

on Proceed pCont do
(
	t = pCont.getTimeStart() as float
	if t == 0 do
	(
		CountMeshes = Meshes .count
		for i = 1 to CountMeshes do
		(	
			pCont.AddParticle()
			pCont.particleIndex = pCont.NumParticles()
			pCont.particleAge = 0
			pCont.particleTM = Meshes [i].transform
			pCont.particleShape = Meshes [i].mesh
		)
	)
)
on Release pCont do
(
