Description

The parameters you use to add an instance of ray tracing axis-aligned bounding boxes (AABBs) to a RayTracingAccelerationStructure.

Use this structure to share parameters across different ray tracing AABBs instances.

Additional resources: RayTracingAccelerationStructure.AddInstance, RayTracingAccelerationStructure.RemoveInstance.

Properties

aabbBufferThe GraphicsBuffer that defines a list of axis-aligned bounding boxes (AABBs).
aabbCountThe number of AABBs Unity uses when you build the acceleration structure for this ray tracing instance.
aabbOffsetThe index of the first AABB Unity uses from RayTracingAABBsInstanceConfig.aabbBuffer.
accelerationStructureBuildFlagsThe flags Unity uses when it builds the acceleration structure for the geometry referenced by this ray tracing instance configuration.
accelerationStructureBuildFlagsOverrideWhether to override the build flags specified when creating a RayTracingAccelerationStructure.
dynamicGeometryWhether the data in RayTracingAABBsInstanceConfig.aabbBuffer is dynamic.
layerThe Layer used by the ray tracing instance.
maskThe ray tracing instance mask.
materialThe Material the ray tracing instance uses.
materialPropertiesAdditional MaterialPropertyBlock properties to apply to the Material.
opaqueMaterialDetermines whether Unity considers the material opaque.
