I might suggest an error catch when the license is not activated and you try and use Octane in Lightwave.
My experience....I deactivated license so I could use at house to continue learning. Came back into office and began to use LW, tried to open a node tree and LW kept hanging. Have to shut down manually via task manager. Did this a couple of times.
Remembered I needed to deactivate license and then went into LW Activated license on this machine and all was good.
Just seems a nice user experience if instead of hanging and crashing Octane would throw an error about the license not being activated to give reminder. May not happen very often but just my experience. Thanks.
