how to update scene obj material from .mat lib using script??

If you want to update the material on an object or collection of objects then this should work:

(
	loadMaterialLibrary ((getDir #matlib)+"\\YourMaterialLibrary.mat")
	
	for obj in $ do
	(
		if isProperty obj #material and obj.material != undefined then
		(
			for mat in currentMaterialLibrary do
			(
				if obj.material.name == mat.name then obj.material = mat
			)
		)
	)
)

Or if you want to update all scene materials with the same name as one in the library then:

(
	loadMaterialLibrary ((getDir #matlib)+"\\YourMaterialLibrary.mat")

	sMatN = for sMat in sceneMaterials collect sMat.name
	
	for lMat in currentMaterialLibrary do
	(
		if findItem sMatN lMat.name != 0 then 
		(
			objs = for obj in geometry where obj.material != undefined and obj.material.name == lMat.name collect obj 
			objs.material = lMat
		)
	)
)

Hope this helps…

You must have at least one object selected or supply your own collection of objects instead of the “$”.
