Vector BlurAdd a gradient based blur to an image.
This node performs a blur operation on an image, but instead of blurring around each pixel uniformly the blur follows a path through the image. The path is determined by vectors extracted from the image itself, pointing in the direction of gradients in the image; for example, in the direction of a downward slope in image luminance. The result is a blur that conforms to details in the original image and produces a look similar to a traditional painting.
These properties control the core behaviours of the node.
|Active||Enables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance.|
|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.|
|Steps||The number of steps that will be taken along the path for a single pixel.|
|Gradient Blur Iterations||The number of pre-blurring operations to perform on the extracted gradient vectors. this helps reduce artifacts in the end result.|
|Orientation||An offset applies to the rotation of the extracted gradient vectors.|
|Softness||Controls how much influence points further along the path have.|
|Step Size||Size of each step taken along each path.|
|Dampening||Controls how much influence the gradients have on the acceleration of the movement along the path.|
|Epsilon||Controls how finely the gradients are calculated. raising this value may help reduce artifacts or precision issues.|
|Normalize||Normalizes the gradient vectors, so the gradient magnitude isn’t used when calculating the paths.|
|Fixed Direction||If enabled, the effect will use only one calculated gradient for the whole path when blurring a pixel. this means the path is a straight line.|
Toggle which of the RGBA channels are affected by the effect.
|Direction Source||Add a texture whose luminance values will be used to drive the Vector blur directions instead.||Video Source|
