Properties[edit]

Property group 'Bounds'[edit]

bUseFixedRelativeBoundingBox[edit]

Type: bool

If TRUE, use the given bounds. If FALSE and a static mesh is set for the source, the static mesh bounds will be used. If FALSE and no static mesh is set, it will use the default bounds (likely not a good thing).

FixedRelativeBoundingBox[edit]

Type: Object.Box

The fixed bounding box to use when bUseFixedRelativeBoundingBox is TRUE

Property group 'Debug'[edit]

bRenderDebugLines[edit]

Type: bool

Debugging helpers

Property group 'Occlusion'[edit]

Type: DistributionFloat.RawDistributionFloat

Structs[edit]

LensFlareElement[edit]

Modifiers: native

LensFlare Element

name ElementName 
The name of the element. (Optional)
float RayDistance 
The position along the ray from the source to the viewpoint to render the flare at.

0.0 = At the source 1.0 = The source point reflected about the view center. < 0 = The point along the ray going away from the center past the source. > 1 = The point along the ray beyond the 'end point' of the ray reflection.

bool bIsEnabled 
Whether the element is enabled or not
bool bUseSourceDistance 
Whether the element value look ups should use the radial distance

from the center to the edge of the screen or the ratio of the distance from the source element.

bool bNormalizeRadialDistance 
Whether the radial distance should be normalized to a unit value.

Without this, the radial distance will be 0..1 in the horizontal and vertical cases. It will be 0..1.4 in the corners.

bool bModulateColorBySource 
Whether the element color value should be scaled by the source color.
Object.Vector Size 
The 'base' size of the element
array<MaterialInterface> LFMaterials 
The material(s) to use for the flare element.
DistributionFloat.RawDistributionFloat LFMaterialIndex 
Index of the material to use from the LFMaterial array.
DistributionFloat.RawDistributionFloat Scaling 
Global scaling.
DistributionVector.RawDistributionVector AxisScaling 
Anamorphic scaling.
DistributionFloat.RawDistributionFloat Rotation 
Rotation.
DistributionVector.RawDistributionVector Color 
Color.
DistributionFloat.RawDistributionFloat Alpha 
DistributionVector.RawDistributionVector Offset 
Offset.
DistributionVector.RawDistributionVector DistMap_Scale 
Source to camera distance scaling.
DistributionVector.RawDistributionVector DistMap_Color 
DistributionFloat.RawDistributionFloat DistMap_Alpha
