Camera Fade

Menu Path : Output > Camera Fade

The Camera Fade Block fades out particles when they are too close to the near plane of the camera. It calculates an interpolation of the current depth between provided its Faded Distance and the Visible Distance properties to determine the amount of fade to apply. To fade particles, this Block modifies their color and/or alpha attributes.

If you input a Faded Distance that is greater than the Visible Distance, the result is that particles fade in as they come close to the camera, rather than fade out as they come close.

Block compatibility

This Block is compatible with the following Contexts:

• Any output Context

Block settings

Setting	Type	Description
Cull When Faded	Bool	(Inspector) Indicates whether to cull the particle culled when it is fully faded to reduce overdraw.
Fade Mode	Enum	Specifies how to fade the particle out when it gets near the camera. The options are: • Color: Fades out the particle's color. • Alpha: Fades out the particle's alpha. • Color And Alpha: Fades out both the particle's color and its alpha.
Affect Shadows	Bool	(Inspector) Indicates whether the fade also affects shadow maps or not. Note that applying the fade to shadows might produce unexpected results when using multiple cameras.

Block properties

Input	Type	Description
Faded Distance	float	The distance from the camera at which to fully fade out the particle.
Visible Distance	float	The distance from the camera at which to begin to fade out the particle. At this distance, the particle is fully visible. Between this distance and Faded Distance, the particle fades out.
