ArtRage uses a very different visual style than most other image editing packages. In most packages, the colours for each layer and pixel are just transfered 'as is' to the screen.
In ArtRage, we work as if all the colours are physically painted onto a surface. That surface has rounghness and texture of its own. We then apply a 3D lighting model to the result. The end result is similar to, but not the same as other packages.
In ArtRage, when you apply oil paint, it has *real* depth and lighting. It interacts with the *real* texture of the canvas.
So there will always be a difference between what you see in another package, and what you see in ArtRage.
Additionally, if you have metalic paints or metalic canvas, the effect is much more obvious, as the metalics interact with the lights much more.

"Sure - how hard can it be?"
