Method

Post-FX nodes are mostly effects added onto an image, after the scene is rendered. These can vary from Colour Correction to FXAA antialiasing, and are generally used to enhance an image. The order of operations are decided based on the Y value of the node in the nodegraph, or the X values if the Y values are the same. Nodes with larger X or Y values will be calculated first.
Unlike the Video Processing Nodes (many of which are shared with these nodes), these nodes only affect the parent, and do not contain a copy of the image.

Post-FX can be applied directly to these nodes, however if applied to other nodes it will affect the whole scene, not just the parent node.

Post-FX have been seperated into 9 groups:
