 |
ERayTracingSceneLifetime |
Lifetime |
Defines whether data in this scene should persist between frames. |
 |
uint32 |
NumCallableShaderSlots |
Defines how many different callable shaders with unique resource bindings can be bound to this scene. |
 |
uint32 |
NumMissShaderSlots |
At least one miss shader must be present in a ray tracing scene. |
 |
TArray< uint32 > |
NumNativeInstancesPerLayer |
Total flattened number of ray tracing geometry instances (a single FRayTracingGeometryInstance may represent many) per layer. |

Unique list of geometries referenced by all instances in this scene. |
 |
TArray< uint32 > |
SegmentPrefixSum |
Exclusive prefix sum of instance geometry segments is used to calculate SBT record address from instance and segment indices. |
 |
uint32 |
ShaderSlotsPerGeometrySegment |
This value controls how many elements will be allocated in the shader binding table per geometry segment. |
