UPDATE: This plugin is quite old. Denis Potonniers has created a nodal pixel filter plugin wich is far more advanced: Please use this instead.
This plugin consists of two plugins, the tibe3_node (after adding found under the pixel filter entry, and tibe3_PFOut, (wich can be only activated inside the tibe3_node editor.)
Unlike others this pixel editor does not apply to the complete image, but only on these parts where an actual object is located
I'm feeling a bit unconfortable releasing this node editor, because we currently have multible versions of this kind of editor, all doing almost the same.For this reason mine can only be applied to objects, not to background (Also because of the reason he uses the rayshade access structure to readout the values)
