I wanna know whether i can export Blender’s compositing nodes to Luxrender. I mean after i stop a render in Luxrender, Blender’s compositing nodes will perform the compositing. If this is not possible than how will i perform different compositing effects like RBG curves and Blurs and many others that Luxrender does not have. And can i export the stamp too to Luxrender so that when a render is stopped, the details of my image are automatically printed?
You can’t directly, but you can take the rendered image and add effects to it in the compositor.
You can also render different passes manually and then combine them in the compositor.
With pylux you can composite the render in blender, but not with layers.
