A variety of Extension Pack tools can be controlled via Environment Variables. Below is a list of Environment Variables, Extension Pack will read

• Licensing
• Connection Time Out
• Material Templates
• Project Templates
• 'Add Channels from Node' Presets

• Licensing

Extension Pack can be licensed for multiple users using an Environment Variable pointing to a (floating) license file.

A license file can be generated after successful activation via the Licensing Dialog in the Help menu.

• MARI_EP_LICENSE_FILE_PATH

Extension Pack will try to verify your license via a License Server. The Environment Variable below determines the Number of Seconds, before

the Connection times out. By default Extension Pack will wait 4 seconds for a License Server response.

Setting a higher value can help when you have a slow connection, setting a  lower value can reduce Time it takes to load Extension Pack.
