Specifies how Unity builds the acceleration structure on the GPU.
Note that some flags might not be compatible with each other.
Additional resources: Settings, RayTracingMeshInstanceConfig, RayTracingAABBsInstanceConfig, BuildSettings.
| None | Specify no options for the acceleration structure build. |
| PreferFastTrace | Build a high quality acceleration structure, increasing build time but maximizing ray tracing performance. |
| PreferFastBuild | Build a lower quality acceleration structure, minimizing build time but decreasing ray tracing performance. |
| MinimizeMemory | Minimize the amount of temporary memory Unity uses when it builds the acceleration structure, and minimize the size of the result. |
