  • translucency_sort_priority (int32): [Read-Write] Translucent objects with a lower sort priority draw behind objects with a higher priority. Translucent objects with the same priority are rendered from back-to-front based on their bounds origin. This setting is also used to sort objects being drawn into a runtime virtual texture.
