node tree to image file?

I have an image here:


I really like the look of it but for what I’m doing need it to be in image form. i found this:

but this allows adds the light to it (seen here)


Any idea how I remove the light and get it to be the same lightness all over?

I am making it for Source filmaker as well so will the shininess still show? ( This question may be for another sub-forum)

The method changed a bit in the last versions.

All you have to do is: choose ‘Diffuse’, and set ‘Color’ instead of ‘Direct’ (read the link above for details).
