PowerCoreTools is a script for 3ds Max that controls CPU usage during rendering. At render start it automatically sets the render process priority and affinity — the number of CPU cores the render process uses — and restores the initial settings when rendering is done. The result is a workstation that stays responsive for other tasks while a render runs, including a second 3ds Max session that can be used to continue work on different tasks.
The tool can be configured to run in a completely transparent No-UI mode, launched right after 3ds Max starts. On-screen UI elements carry tooltip pop-ups with detailed information. As a tool aimed at advanced usage, it presumes basic knowledge of CPU priorities and affinity settings.
Version 1.2 adds 3ds Max 2017+ compatibility and support for the ART renderer. MaxToArnold support is currently limited, as that renderer manages CPU resource usage by itself. PowerCoreTools was created by Josef 'spacefrog' Wienerroither and requires 3ds Max 2010 or higher.
