| renderer | The Renderer associated with the ray tracing instance. |
Marks the geometry of the ray tracing instance as dirty.
| handle | The handle associated with the ray tracing instance. |
Only ray tracing instances that use RayTracingMode.DynamicGeometryManualUpdate can use this function to update their geometry. The function doesn't have any effects on ray tracing instances using procedural geometries (AABBs).
To trigger an acceleration structure build on the GPU, call RayTracingAccelerationStructure.Build or CommandBuffer.BuildRayTracingAccelerationStructure. After invoking one of these functions, the geometry is not considered dirty anymore.
