I’m having trouble rendering out premultiplied tga files. I have a simple volume light that I’m rendering and saving as a premultiplied tga. There’s no problem with regular mesh objects in the scene, but when I import the image into Combustion and set the footage as premultiplied, I’m getting the wrong colour for the volume light. It looks greenish when it should be blue. My background settings in max, everything else I can think of a are fine. If I view the tga without transparency, the colour is perfect.

Why is the volume light giving me the wrong colour when premultiplied and how can I fix it?

Thanks
Mark
