Scripting - catching an error for a none existent item

["Adam Seeley" <adam.seeley(at)clearpost.co.uk>]

Hi,

Another basic scripty question (in VB).

I'm looping through the Partitions in a Pass and printing out the Material names.
This is fine if there is a Material, but falls over if none exists.
How do I check to see if it exists at all before I hit an error?

E.g. 
		for each oPartition in oPartitionList 

			logmessage oPartition.name
			if oPartition.Material <> false then logmessage "MATERIAL : " & oPartition.Material.Name	
					
		next

Will give

'INFO : Background_Objects_Partition
'INFO : MATERIAL : Scene_Material
'INFO : Background_Lights_Partition
'ERROR : Object variable not set - [line 27]


Thanks again,

Adam.
