struct FExteriorVisibilitySampling
Remarks
Parameters controlling how exterior visiblity is tested.
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
bool | bDoubleSided | Whether to treat faces as double-sided. |
 |
bool | bMarkDegenerateAsVisible | Whether to mark degenerate tris as visible. If bPerPolyGroup is true, this setting controls the classification of PolyGroups that only have degenerate tris. |
 |
int32 | NumSearchDirections | Number of directions to test for visibility. |
 |
double | SamplingDensity | Approximate spacing between triangle samples used for visibility tests. |
