Each processing node requires to be activated with the separate license of Metashape Professional. Metashape Professional instance that is acting as a network processing server does not require to be activated.

So, for example, for a solution with 1 server and 10 processing nodes working simultaneously (all running on 11 different computers), it is required to have 10 node-locked licenses activated on each node, a floating license with a count 10 accessible by all nodes, or a combination of node-locked/floating licenses with the total number of 10.
