Blur

2D Modifier - Quick-to-create multi purpose blur

This blur allow you to, of course, blur your image but thanks to advanced parameters, you'll be able to create several effects with it, such as bloom effects.

Shapes

Here is a little preview of various shapes available inside this Blur:


Note that you can then create advanced custom shapes to create complex blurs. To access to that feature and create new custom Blurs, here is the procedure:


You can then switch between the different algorithms used to combine Blurs:
- Multi-pass : Calculate one blur after the other as a chain of effects
- Combine : Calculate all blurs in the same time, combining shapes
- Fast Combine : Does the same thing that "Combine" but...faster. Only issue is that it cannot use all the shapes.
Fast combine cannot use "sprite" and "multi-pass" as a shape for instance.

Budget and Quality

A little explanation about the Budget / Down sampling parameters:
The Budget is basically the quality of your Blur, the number of samples it will use. The "perfect budget" information to the right show you the number of samples required to have a perfect blur depending on the size of your blur.
As you see, is you change the size of the Blur, the perfect budget indication will change as well. And the wider your blur become the more it will be down-sampled. This mean that the sample used will have a lower quality:


Of course this automatic down-sampling can be deactivated, allowing you to keep high-quality samples whatever the radius:


We are in real-time though, be cautious with theses parameters.

Mask Interpretation

This blur allow different kind of mask interpretation mode, the default mode is "Fade":
Fade Interpretation Mode : The feather of the mask will have an effect over the opacity of the blur
Radius Interpretation Mode : The feather of the mask will have an effect over the radius of the blur
Fade and Radius Interpretation Mode : The feather of the mask will have an effect over both the opacity and the radius of the blur
To change this option, go inside the advanced parameters as showed below:


Here is a Ring Blur with a "gamma" aggregator type over a simple line. This blur is masked with a simple placement mask and a feather:

Fade Mask Interpretation


Radius Mask Interpretation


Fade and Radius Mask Interpretation



Radius Mask Interpretation allow to do nice tilt-shift effect over a 2D Image:


And now, here is a preview of the shapes, as 2 custom examples (one in multi-pass and one in combine):

Gaussian Blur set as "Normal" Blending mode with varying luminosity threshold


Gaussian Blur set as "Screen" Blending mode with varying luminosity threshold


Gaussian in "Normal" Blending mode and cycle through all aggregator types


Box Blur


Circle Blur


Ring Blur


Hexagonal Blue


Hexagonal Blur in "Screen" mode with "Maximum" aggregator type and varying luminosity threshold


Zoom Blur


Spin Blur


Directional Blur


4 Star Blur


8 Star Blur


Random Box Blur


Random Circle Blur


Random Triangle Blur


Random Triangle with "Smoothing" parameter variation


Diffuse Blur


Custom : Multi-Pass algorithm with 2 directional blur (one still and one rotating)


Custom : Combine algorithm with 2 directional blur (one still and one rotating)


Custom : Multi-Pass algorithm with a diffuse and a radial blur



Parameters

  • Radius of the blur in pixel, this will affect the size of the blur
  • Shape of the blur. You have choice between all the classical radial / spin / directional etc. and here you can also change your shape to "Custom" to create your own custom blur
  • Quality of the blur. This won't affect the size of the blur. To know which level of quality you need to have a perfect blur in function of it's size, check the "Budget" Attribute
  • Configure here the blending modes and filters for your blur
