Check for existing material

[Pixero]

I want to check if a material (name) exists, and if not create one with that name.
However I can't get the syntax right.
Can't seem to find any reference to it anywhere either.
Here's my try:

if(Sketchup.active_model.materials["MyMaterial"])
		face.material = model.materials "MyMaterial"  #If material exist use it
	else #Else create a new material with that name
		face.material = Sketchup;;Color.new(100,100,100) 
		face.material.name = "MyMaterial"
	end

` model=Sketchup.active_model
mats=model.materials
mname="SomeMaterialName"
unless mat=mats[mname] ### nil if no match
mat=mats.add(mname) ### reference to the new material

set up 'mat' properties - RGB, alpha etc...

end The variable ' mat' points at the material named ' mname'. If it's 'new' then you can set its properties, otherwise it be opaque/black ! ... Finally use face.material=mat` ...

Thanks. Its working now.
