Tilt Shift is a local blur effect that blurs the image based on distance to the center. It comes in two modes: TiltShift and Iris. The following screenshots demonstrate the difference.
As with the other image effects, you must have the Standard Assets Effects package installed before it becomes available.
Property: | Function: |
---|---|
Mode | Choose type of defocus (see above). |
Quality | Amount of samples taken and thus responsible for performance. Choose Preview to just render blur areas. |
Max Blur Size | Maximum blur distance allowed. |
Blur Area | Size and strength of the blur (verify effect with Preview Quality). |
This effect requires a graphics card that supports Shader Model 3. See the Graphics Hardware Capabilities and Emulation page for further details and a list of compliant hardware.
