I don't think that there's an RiOption to specify the number of threads.

However, you can specify the number of threads on the command line in the output driver.

i.e. change the “prman” to “prman -t:2”

Thanks.

prman -p:n

n = cpu cores

Shameless quote from the renderman docs:

Because prman consumes much less memory when using threads than when launching multiple processes, the default behavior for prman is to only utilize threading. If the user specifies -p:n, it will be interpreted as -t:n. If both -t and -p are used, only the value provided via -t will be considered. This default behavior can be reverted to the old multi-process behavior by placing the following in the rendermn.ini file:

/prman/parallelmode multiprocess

The user can also change the default number of processing units with a setting in the rendermn.ini file:

/prman/nprocessors 1

This is useful if one wants to override the default behavior, which queries the system for the number of processing units available. If the nprocessors setting is found, it will use that setting instead of querying the system. Note, this setting affects the default number of processing units utilized when using the -p:n option as well.



So -t works too…
