Attributes
Name |
Description |
Active |
Turn the effect on or off. Values < 0.1 will turn the effect off, and deferred rendering must be on. |
Blend Amount |
Changes the opacity of the new effect over the original image. |
Blend Mode (RGB) |
Change how the generated effect blends with the parent image RGB. |
Blend Mode (Alpha) |
Change how the generated effect blends with the parent image alpha. |
k1 |
First radial distortion coefficient. Barrel distortion typically will have a negative term for k1 whereas pincushion distortion will have a positive value. |
k2 |
Second radial distortion coefficient. |
k3 |
Third radial distortion coefficient. |
Distortion Scale X |
The distortion scale amount in X. |
Distortion Scale Y |
The distortion scale amount in Y. |
Affect Channels
Select which of the RGBA colour channels are affected by the effect.
