Arnold Performance Improvements
Significant updates to Arnold greatly improve rendering performance for scenes with complex hierarchies and point instancers. Time to first pixel, interactivity in IPR, and scene processing time for batch renders are also faster.
- Faster procedural instancing: Arnold is faster at rendering scenes with complex hierarchies and point instancers. The new
options.procedural_instancing_optimizationflag usually produces speedups between 1-2x, but for sufficiently complex scenes the speedup can be significantly larger. This new optimization defaults toexhaustivemode, which gives the most speedup. Exhaustive mode may use more memory; you can switch toconservativemode to use only the optimizations that do not consume additional memory. This setting is currently only supported for batch CPU rendering. (ARNOLD-14208)

- Better scaling for parallel scene init/update: The parallel scene init and update are now faster than before, especially on many-core machines. Time to first pixel, interactivity in IPR, and scene processing time for batch renders has improved. (ARNOLD-14902, ARNOLD-15718, ARNOLD-15974, ARNOLD-16114)
