Thanks for the reply both of you.

I am using Vue 6 xstream version.

Rutra by loading the backdrop and then deleting it will the object in the scene still be lit by the backdrop?

What I want to achieve is lighting objects in a scene, rendering and then exporting as a TGA without the hassle of then rotoscoping the background image out. If I placed a plane behind the object and made it completely black then maybe I could matte it out? However if the backdrop is deleted and still my scene object is lit perhaps that would be the best way, as the background would just be black. I will have a fiddle.

Cheers Guys
