That did the trick! Thanks Thomas! What a great set of plugins you've developed!

Hi everyone. here's my conundrum. I am importing trees from Onyx Tree (in 3DS format)and when I do the leaves come in as double-sided geometry. The underside of the leaves are the correct materials and color, but the upper sides of the leaves show the default blue-gray texture. I've tried to select all the similar materials to change them all at once, but it doesnt work. Is there another way I can handle making the leaves all one color on both sides? Preferably without having to select them enmasse or a few at a time?

I've included a screenshot to help clarify the issue.
