  • Possible to restrict core usage for Net Render (a.k.a. Set Affinity)?

    I have a small render farm - two workstations and one dedicated render server.

    I would like to use both workstations for Net Render (as well as the dedicated box), but don't want to use 100% of the available cores on my co-worker's workstation. I have the ability on my own computer to (via the Task Manager) "Set Affinity" on the 3dsmax.exe process to specify how many cores Max can use. My coworker does not have that ability since the Max process is being launched from my computer. Since neither of us have Admin rights, we can't "Show processes from all users" so he can't even see the active 3dsmax.exe task that was initiated by my computer - Thus, he can't "Set Affinity" on the Max process.

    It seems like I remember a way to specify the individual cores via the IP address when you assign a server in the Distributed Rendering settings - something like 0.0.0.0:01. Am I remembering this correct?

    All you have to do is select the "server" process and set your affinity there. That will auto translate to the newly opened max window on render.

      put to folder ..3dsmax201x\scripts\startup\ a file called "limit.ms"
      inside is line

      renderers.current.system_numThreads=4

      4 is the cpu core used by 3ds/vray - put any numer you like

        Thank you for the responses - I'm just now seeing them. Will give these a try!
