afaik Face Material ID can't be animated, use animated Material modifier instead.

animate material

oh! i was hoping to animate the keys with mis script and add the material animation at the same time. ill have to use a material modifier within the script. thanks man

You can also wire the value of Material modifier to some animated node like helper or use script controller to set the value dynamically. Here's the example:


delete objects

mtl = Multimaterial()
for i=1 to 10 do (
	
	m = Standardmaterial()
	m.diffuse = ([25,25,25] * i) as color
	mtl.materialList[i] = m)

pt = point pos:[0,0,10] centermarker:on cross:off wirecolor:yellow
animate on (
	
	at time 0f  pt.pos = [0,0,10]
	at time 99f pt.pos = [400,0,10]
	
)

mtlMod = Materialmodifier()
mtlMod.materialID.controller = float_script()
mtlMod.materialID.controller.script = "self = refs.dependentNodes this firstOnly:true
if self == undefined then 1 else (

	id = (distance self.pos $point001.pos)/10.0
	id = if id > 10 then 10 else (int)id	

)"

for i=0 to 20 collect (
	
	b = box width:18 length:50 height:5
	b.pos = i * [20,0,0]
	b.material = mtl
	convertToMesh b
	addModifier b (copy mtlMod)	
	b
	
)
