Raytrace Acceleration group
Choose BSP as the Raytrace Acceleration method.
When you choose BSP as the Raytrace Acceleration method on the Rendering Algorithms rollout, the parameters described here are displayed. BSP stands for Binary Space Partitioning.
NoteIf the scene contains too many faces (triangles) to fit in a tree of the size specified by the Size and Depth parameters,
mental ray disregards the Size value and creates larger leaf nodes. This can significantly slow down rendering. To avoid this
problem, increase the value of Depth.
Interface
- Size
-
Sets the maximum number of faces (triangles) in the leaf of a BSP tree. Increasing the Size value reduces memory consumption
but increases rendering time. Default=10.
- Depth
-
Sets the maximum number of levels in the BSP tree. Increasing the Depth value reduces rendering time, but increases memory
consumption and preprocessing time. Default=40.
TipFor large scenes, increasing the Depth value to 50 or more can greatly improve rendering time.
