Tilt Shift
The Tilt Shift image effect is a specialized Depth of Field effect that demonstrates how to enable very smooth transitions between focused and defocused areas. It is also is easier to use and has generally less possible image artefacts. However, as it is among other things relying on dependent texture lookups, it can also be more expensive.
Tilt shift example. Observe the overall achieved smoothness of the effect.
As with the other image effects, this effect is only available in Unity Pro. Make sure to have the Pro Standard Assets installed.
Properties
| Focal Settings | |
| Visualize | Visualizes the focal areas in the game view with a green tint. |
| Distance | The distance to the focal point from the camera position in world space. |
| Smoothness | The smoothness when transitioning from out-of-focus to in-focus areas. |
| Background Blur | |
| Downsample | Downsamples most internal buffers (Makes the effect faster and more blurry). |
| Iterations | Number of iterations for blurring the background areas (all things behind the focal area). |
| Max Blur spread | The maximum blur distance for the defocused areas. Makes out of focus areas proceedingly more blurry. |
| Foreground Blur | |
| Enable | Enables foreground blurring. This will make the effect more expensive. |
| Iterations | Number of iterations for blurring the foreground areas (all things in front of the focal area). |
Hardware support
This effect requires a graphics card with pixel shaders (3.0) or OpenGL ES 2.0. Additionally, depth texture support is required. PC: NVIDIA cards since 2004 (GeForce 6), AMD cards since 2005 (Radeon X1300), Intel cards since 2006 (GMA X3000); Mobile: OpenGL ES 2.0 with depth texture support; Consoles: Xbox 360, PS3.
All image effects automatically disable themselves when they can not run on end-users graphics card.
