Rangooo 10 Posted April 12, 2017 I have a problem and can not go on and if I want to pack with Pboprojekt the PBO I always get this error. The source or terrain builder is closed and everything else is not used. Share this post Link to post Share on other sites
Dwayne_ 3 Posted May 12, 2017 Go onto Steam and hover over 'LIBRARY', a drop down list will appear and select 'Tools'. You will find Arma 3 Tools. Download and install this. When you run the program you will find a program called Addon Builder, use this to create .pbo's. Share this post Link to post Share on other sites
