A variable quality blur that ranges from very low quality to very soft.
— Horizontal and Vertical Strength: These sliders let you adjust the width and height of blur.
— Same Horizontal/Vertical: This checkbox lets you adjust these parameters together or separately.
— Number of Iterations: Controls how smooth the resulting blur is, with 1 being the lowest and most “boxy” level of quality and 6 being the highest and smoothest level of quality. At low iteration values, box blurs can appear somewhat similar to lens blurs.
— Border Type: Lets you choose how the edges of the image are affected by this blur, options include Black, Replicate, Reflect, and Wrap Around.
— Blur Alpha: Check this box to blur the Alpha channel along with the image’s content.
Directional Blur
A blur that’s constrained to a single angle.
— Blur Strength: How much blur you want.
— Blur Angle: The direction of blur.
— Blur Type: When Blur Type is set to Realistic, the blur effect emulates a photographic motion blur. When set to Stylized, the blur effect is a simple and smooth digital blur.
— Symmetric Blur: When the Symmetric checkbox is turned on, the blur effect appears to be created from both directions, with the result being more of a double-image that’s blurring along the blur angle, simulating motion blur in a camera. When off, the blur effect appears to be moving in a single direction, from the original position out along the blur angle.
— Border Type: Lets you choose how the edges of the image are affected by this blur; options include Black, Replicate, Reflect, and Wrap Around.
— Blur Alpha: Check this box to blur the alpha channel along with the image’s content.
Gaussian Blur
Provides a smooth blur that resembles looking at the image through semi-opaque glass, reducing detail and noise.
— Horizontal and Vertical Strength: Two sliders let you adjust the Horizontal and Vertical Strength independently.
— Same Horizontal/Vertical: This checkbox lets you keep the Horizontal and Vertical Strength values ganged together.
— Border Type: Lets you choose how the edges of the image are affected by this blur; options include Black, Replicate, Reflect, and Wrap Around.
— Blur Alpha: Check this box to blur the Alpha channel along with the image’s content.
