Particles Shader

The Particles shader is used to render particle effects for fire, smoke, lightning, sparks, and fog that are affected by light, and as such cast shadows and cause reflections.

Shader Parameters

Color lookup amplitude
Sets the color lookup brightness and multiplier.
This parameter requires that the Color lookup shader generation parameter is enabled.
Default value: 1

Color lookup color phase
Sets the per-color phase to be used.
This parameter requires that the Color lookup shader generation parameter is enabled.
Default value: 1

Sets the amount of global illumination.
Default value: 1

Perturbation amount
Controls the amount of deformation that is used.
This parameter requires that the Screen space deformation shader generation parameter is enabled.
Default value: 0.01

Perturbation anim speed
Controls animation translation speed and frequency that is applied to the deformation map.
This parameter requires that the Screen space deformation shader generation parameter is enabled.
Default value: 0.05

Perturbation tiling

Refraction Bump Scale
Sets the refraction bump scale.
This parameter requires that the Refraction shader generation parameter is enabled.
Valid value range: 0 - 2.0
Default value: 0.1

Soft particles scale

This parameter requires that the Depth Fixup shader generation parameter is enabled.
Default value: 0.05

Shader Generation Parameters

Refraction
Enables the use of a bump-map texture as the displacement for refraction.

Refraction Tinting
Enables the use of a color texture to tint refraction.

Screen space deformation
When enabled, the Refraction Normal texture map slot also becomes available under Texture Maps.

Deformation
When enabled, the Deformation Normal texture map slot also becomes available under Texture Maps.

Color lookup
Enables the use of the color lookup map for applying color lookup. When enabled, the Color Lookup Map texture map slot also becomes available under Texture Maps.

Specular Lighting
Enables the calculation of specular lighting in addition to diffuse lighting.

Depth Fixup
Enables writing depth for depth of field and post processing.
