The optimized Blur image effect blurs the rendered image by filtering in a number of passes using a gaussian filter curve.
The following screenshots show possible blur results.
 
 
As with the other image effects, you must have the Standard Assets Effects package installed before it becomes available.
| Property: | Function: | 
|---|---|
| Downsample | The number of times the image will be downsampled before the blur is applied. Bigger blurs and faster speeds can be expected the more you downsample. | 
| Blur Size | The spread used when filtering the image. Higher values produce bigger blurs. | 
| Blur Iterations | The number of of times the filter operations will be repeated. | 
This effect should run on all hardware that Unity supports.
