Legacy Blur

2D Modifier - Blur the image

Types of blur

Here are the different types of shapes that are supported by legacy blur. These shapes are configurable in the Parameters editor:

Gaussian

Box

Hexagonal

Spin

Radial

Directional

Circular

Random

Diffuse

In addition to the choice of the shape, other parameters such as lightness and down-sampling can be configured. Here are three examples of legacy blur presets:

Bloom

Glow

Frozen window

Here are more examples on the effect of the size and lightness parameters:

No Blur

Size: 1 - Down Sampling 1/1 - Base size: 20px

Size: 1 - Down Sampling 1/1 - Base size: 100px

Size: 4 - Down Sampling 1/1 - Base size: 100px

Size: 1 - Down Sampling 1/6 - Base size: 100px

Size: 1 - Down Sampling 1/6 - Base size: 100px - Source Level: 100%

Size: 1 - Down Sampling 1/6 - Base size: 100px - Source Level: 100% - Lightness: 50%

Blur Parameters

Sample Numbers : The size of the hight quality blur pass (number of samples used)
Samples down Sampling : What level of precision these samples will be. For instance for an image of 64x64 pixels, with a down sampling of 1/32, the blur sample resolution will be of 2x2 pixels
Samples Distance : Size of the low-quality blur pass (how far apart will the samples will be). The more higher the size is (more samples), the more the blur "radius" will seem high. Note that as base size is expressed in pixels, down sampling will also affect this parameter.

Parameters

  • Shape (Legacy Blur Shape) : How the blur samples will be scattered in the image (Circular, Radial, Directional, Gaussian blurs, ect)

    Parameters common to all Elements

    • Loading (Activation State) : The loading status of the legacy blur shape. It can be loaded , enabled by not loaded or unloaded
    • Activation (Activation State) : The activation status of the legacy blur shape. It can be active , enabled by not active or inactive
    • Color Label (sRGB Color) : Associate a color label to your legacy blur shape to make it easily locatable
    • Solo (On/off option) : Activate this to keep only this legacy blur shape active and hide all other legacy blur shapes in same location
    • Editable (Activation State) : The editabiliy status of the legacy blur shape. It can be locked directly , locked indirectly or editable
    • Preset (Element Preset Selector) : Select a preset to apply on the legacy blur shape
    • Status (Object's errors and warnings) : Warnings and errors associated to this legacy blur shape
  • Additional Brightness (Percentage (-100% - 100%)) : Control the lightness added to the blurred image (useful for glow/bloom effects, if used with the sourceLevel at 100%)
  • Source Level (Percentage) : How visible the un-blurred source will be (useful to create glow/bloom effects)
  • Pixel Type (Pixel Type) : Depth of the Pixel of the legacy blur. Can be used to increase the pixel depth of an image (useful when displacing a mesh for instance)
