Hi,
Thanks for your swift reply. You can enable the log by setting General - Log Level to Debug in any Forest object in your scene, before sending it to the renderer. - within the Exiting BuildMesh you should find the corresponding info of generated items. The log file is located at:
C:\Users\<yourUsername>\AppData\Local\Autodesk\3dsmax\<max version>\ENU\Network\Max.log
I hope that helps.
Best regards,
