Structs
CompartmentRunList
Modifiers: native
For specifying which compartments should run on a given frame
- bool RigidBody
- The rigid body compartment will run on this frame
- bool Fluid
- The fluid compartment will run on this frame
- bool Cloth
- The cloth compartment will run on this frame
- bool SoftBody
- The soft body compartment will run on this frame
Default values:
| Property | Value |
|---|---|
| Cloth | True |
| Fluid | True |
| RigidBody | True |
| SoftBody | True |
LightmassWorldInfoSettings
Modifiers: native
- float StaticLightingLevelScale
- Scale of the level relative to Gears of War 2 levels.
All scale-dependent Lightmass setting defaults have been tweaked to work well in Gears 2 levels, Any levels with a different scale should use this scale to compensate.
- int NumIndirectLightingBounces
- Number of times light is allowed to bounce off of surfaces, starting from the light source.
0 is direct lighting only, 1 is one bounce, etc. Bounce 1 takes the most time to calculate and contributes the most to visual quality, followed by bounce 2. Successive bounces are nearly free, but have a much lower impact.
- Object.Color EnvironmentColor
- Color that rays which miss the scene will pick up.
This is effectively a light surrounding the entire level that is shadowed, but doesn't emit indirect lighting.
- float EnvironmentIntensity
- Scales EnvironmentColor to allow independent color and brightness controls.
- float EmissiveBoost
- Scales the emissive contribution of all materials in the scene.
- float DiffuseBoost
- Scales the diffuse contribution of all materials in the scene.
- float SpecularBoost
- Scales the specular contribution of all materials in the scene.
- float IndirectNormalInfluenceBoost
- Lerp factor that controls the influence of normal maps with directional lightmaps on indirect lighting.
A value of 0 gives a physically correct distribution of light, which may result in little normal influence in areas only lit by indirect lighting, but less lightmap compression artifacts. A value of .8 results in 80% of the lighting being redistributed in the dominant incident lighting direction, which effectively increases the per-pixel normal's influence, But causes more severe lightmap compression artifacts.
- bool bUseAmbientOcclusion
- If TRUE, AmbientOcclusion will be enabled.
- float DirectIlluminationOcclusionFraction
- How much of the AO to apply to direct lighting.
- float IndirectIlluminationOcclusionFraction
- How much of the AO to apply to indirect lighting.
- float OcclusionExponent
- Higher exponents increase contrast.
- float FullyOccludedSamplesFraction
- Fraction of samples taken that must be occluded in order to reach full occlusion.
- float MaxOcclusionDistance
- Maximum distance for an object to cause occlusion on another object.
- bool bVisualizeMaterialDiffuse
- If TRUE, override normal direct and indirect lighting with just the exported diffuse term.
- bool bVisualizeAmbientOcclusion
- If TRUE, override normal direct and indirect lighting with just the AO term.
Default values:
| Property | Value | ||||||||
|---|---|---|---|---|---|---|---|---|---|
| bUseAmbientOcclusion | False | ||||||||
| bVisualizeAmbientOcclusion | False | ||||||||
