Multiple States

The FGI pipeline supports a 'day/night' cycle of states, in which each state contains all the lighting information required to render the scene.

For example:

• The sun position

• The ambient color

• The shadows color

You can specify which lights in the scene affect a certain state to simulate day and night conditions.

You can also specify which lights affect the LightProbes generation and which lights are used in real time.

For each state, a different set of LightProbes Global Illumination data is calculated.

State parameters used during rendering

Some parameters are used during the final rendering of the image, such as:

• lightsContribution

• probesContribution

• shadowsColor (CSM shadows, only when realisticShadows is Off)

• shadowsContribution (CSM shadows)

State parameters used when generating LightProbes

Some parameters are used only when generating the LightProbes:

• genAmbientColor

• genSunContribution

• genLightsContribution

• genShadowsColor (CSM shadows, only when realisticShadows is Off)

• genShadowsContribution (CSM shadows)
