Fx

To access FX tool click on Tools->Fx in Main menu or press the FX icon button on the toolbar as showed in the following image:

The Fx tool lets you to build Time Of Day transitions, control weather conditions, edit ocean and other environment features, and edit post processing effects.
It is composed by 2 panels:

1. Parameters modifier
2. Time Of Day timeline

Parameters modifier contains 3 tabs that lets you to access respectively to:

• Weather
• Post Processing
• Environment

Weather

Weather parameters let you to modify atmospheric conditions at a given time of day. Parameters are grouped into various sections:

• Sky Modify the look of sky
• Sun Effects of the sun on the whole environment
• Storm Storm configuration
• Sea Ocean conditions you can change basing on time of day
• HDR Some HDR parameters you can change basing on the time of day

Warning

Every time you modify a weather parameter you must Record the keyframe into the timeline of Time Of Day panel to avoid loosing your settings.

Sky

Parameter	Description	Example
Mie	Mie Scattering
Ray	RayLeigh Scattering
In	In Scattering: changes overal luminosity of the sky
Anis	Anisotropic scattering: changes the dimensions of sun disk
WaveR	Red component of sky molecules scattering: change the overall color of sky and atmosphere
WaveG	Green component of sky molecules scattering: change the overall color of sky and atmosphere
WaveB	Blue component of sky molecules scattering: change the overall color of sky and atmosphere
Ext	Extinction: changes the overall density of fog
Clouds	Clouds coverage
Fog	Fog Color
Zenith	Sky color at Zenith: this value is multiplied for ZenMul value and added to the base sky color. Useful at sunset, sunrise and night.
Horizon	Sky color at horizon: this value is multiplied for HorMul value and added to the base sky color. Useful at sunset, sunrise and night.	NONE
FogMul	Fog Color Multiplier
Ambient	Base Ambient color. This value is multiplied by the ambient illumination coming from cubemaps
AmbMul	Base ambient color multiplier
HorMul	Sky horizon color multiplier	NONE
ZenMul	Sky zenith color multiplier	NONE
FogH	Exponential Fog height from sea level. Greater values make fog thinner.
Turb	Sky Turbidity: makes the sky and atmosphere less/more orange
SUN	Sun color: affects the overall sky/clouds/atmosphere color
CldColor	Clouds base color	NONE
CldMul	Clouds base color multiplier	NONE
SmkColor	Smoke particles color. This is multiplied by the color of all particle systems	NONE
SmkMul	Smoke particles color multiplier	NONE
pRatio	Sky particles ratio: greater values make sky more blue.
Amb Scatter	Overall scene ambient scatter. Useful in night scenes.

Sun

Parameter	Description	Example
Pow	Intensity of the sun light. NOTE: It doesn't affect the sky but all objects of the scene.
SunLight	Color of the sun light. NOTE: It doesn't affect the sky but all objects of the scene.
GrMul	God Rays effect intensity multiplier
MoonCol
MoonMul
CldSpec
CldDiff
ReflMul	All scene reflections are multiplied by this value. Useful during night conditions, for mitigating too bright reflections.
SmkSpec
MoonGlow
ReflGroundColor	Color of the ground rasterized into the global ambient cubemap. Global ambient cubemap is computed taking into account sky colors and ground color
