Bloom and Flares Image Effect

The Bloom and Flare image effect adds image based bloom and lens flares to the image.

Example use showing both glow and lens flares based on the skybox' alpha channel. Note how the clouds are thus blocking the light scattering.

As with the other image effects, this effect is only available in Unity Pro. Make sure to have the Pro Standard Assets installed.

Properties


Mode	Chose between advanced or simple configuration modes.
Intensity	The global light intensity of all the added light.
Blur iterations	The smoothness of the bloom and flares.
Blur spread	The spread of the bloom and flare computation.
Threshhold	The light intensity threshhold that defines which image parts are being considered.
Use alpha mask	Defines how much you want to rely on the alpha channel of the color buffer when applying the image effect.
Cast lens flares	Enable or disable lens flares.
Intensity	Overall intensity for all lens flares.
Threshhold	The light intensity threshhold that defines which image parts are being considered for lens flares.
Mode	The kind of lens flares that should be cast. Chose between Ghosting, Hollywood or a combination of both.
Color	The color of the first lens flare.
Color	The color of the second lens flare.
Color	The color of the third lens flare.
Color	The color of the fourth lens flare.
Stretch width	The width for the hollywood flare type.
Blur iterations	Smoothness for the hollywood flare type.
Tag	This makes sure that objects with a certain tag will always be bloomed (i.e. if they are bright enough). The alpha channel of the image will be updated for those objects prior to applying the image effect.

Hardware support

Bloom and Flares works only on graphics cards with support for pixel shaders (2.0) or devices with OpenGL ES2.0 support. Eg. GeForce FX 5200 or Radeon 9500 and up. All image effects automatically disable themselves when they can not run on an end-users graphics card. Depth texture support is not required.
