Post-FX
Updated: 26 Mar 2025
Post-FX
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.
- Cameras (Will only come into affect when viewed through the camera)
- Generators
- Render To Texture
- Root (This will affect the whole layer)
- All Video Processing Nodes (although you will mostly use Video Loader and Video Null)
Post-FX have been separated into 9 groups:
- Antialiasing, for nodes that generate better antialiasing.
- Blur, for blurring an image.
- Colour, for changing the colours in an image.
- Distortion, for modifying the shape of an image.
- Generators, use mathematical patterns to affect an image.
- Image Compression, for compressing or decompressing images.
- Image Processing, for general video effects.
- Stylisation, for more intense image modifications.
- Warping, for stretching and squashing images.
