# Fast Blur node

The Fast Blur node applies an approximated Gaussian blur algorithm to its input.

## Inputs

The Fast Blur node accepts an RGBA input to be blurred and an optional blur mask that defines the intensity of the blur effect.

## Outputs

The Fast Blur node outputs the result of the blur operation.

## Parameters

The Fast Blur node has three parameters:

- The resolution defines the size of the output image.

- The sigma parameter defines how smooth the output will be.

- The quality can be modified to choose between nicer result and rendering time.

## Notes

This node outputs an image that has a fixed size.
