Hello, I’m new to Godot
I have an scene (made with Blender) that has two materials. I want to change one of the materials using code. This code illustrates what I want, but doesn’t work (the variable center is the MeshInstance with the two materials):

extends Spatial


const centerMaterials : Array = [
	preload("res://Assets/MapTiles/empty/Center.material"),
	preload("res://Assets/MapTiles/blue/Center.material"),
	preload("res://Assets/MapTiles/green/Center.material")
	]


onready var center = $Circle


func _ready():
	pass


func changeCenter(newCenter):
	center.material/0 = centerMaterials[newCenter]

Have you tried code like this?

func changeCenter(newCenter):
    center.set_surface_material(0, centerMaterials[newCenter])

If not, also try the code center.get_mesh().set_surface_material(0, centerMaterials[newCenter]).

The first solution worked. Thanks!
