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.
|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.
|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.
|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.
|An offset applies to the rotation of the extracted gradient vectors.
|Controls how much influence points further along the path have.
|Size of each step taken along each path.
|Controls how much influence the gradients have on the acceleration of the movement along the path.
|Controls how finely the gradients are calculated. raising this value may help reduce artifacts or precision issues.
|Normalizes the gradient vectors, so the gradient magnitude isn’t used when calculating the paths.
|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.
|Add a texture whose luminance values will be used to drive the Vector blur directions instead.
