Hi,

Do they have specific names (MT_book_001, MT_book_002 ... MT_book_100) or you want to do it by selected objects ?
What is a material structure - I see you have some "material1" after meditMaterials[10]

Are they all inside one Multi/Sub Material ? So you want to change reflectionMap in first one and instance to rest?

Just need to know how to get Array of materials to instance refMap in

But also if you use Vray you can use one VRayMultiSubTex as diffuse with 100 different bitmaps and just one Bitmap as refMap

oki,

try this one:

1. put your first VRayMtl with correct reflection texturemap into 1st slot in Material Editor (it has to be just VRayMtl and not Multi/Sub Mtl)
2. select all objects you want to instance reflection map in
3. run the script:

tm = meditMaterials[1].texmap_reflection
 
for o in selection where o.material != undefined do (
	m = o.material
	if classof m == VRayMtl and findstring m.name "MT_book_" == 1 do m.texmap_reflection = tm
	if classof m == Multimaterial do
		for mm in m.materialList where mm != undefined and classof mm == VRayMtl and findstring mm.name "MT_book_" == 1 do mm.texmap_reflection = tm
	)

Script finds all VRayMtls in selected objects with name starting "MT_book_" and than instance Reflection_texture Map.

Hope it helps.

Hi, sure, try this one:

for o in selection where o.material != undefined and classof o.material == Multimaterial do 
(
	local m = o.material
	m.name = o.name
	for i = 1 to m.materialList.count where m.materialList[i] != undefined do m.materialList[i].name = o.name + "_mtl_" + (formattedPrint i format:"02d") 
)
--to refres Meditor if its open:
if MatEditor.isOpen() do (MatEditor.Close(); MatEditor.Open())
