This article will explain how to generate a log file for troubleshooting graphical errors in Modo. If you are seeing any artifacts in the 3D Viewport or any issues with the UI of Modo, you can manually generate a log file to send to us by launching Modo from a command line with several flags enabled.
This log file will capture information relevant to understanding the cause of the problem.
The commands listed below are examples you can run on each operating system, and they will create a text file on your Desktop called 'modoLog.txt'.
This is the log file we require for troubleshooting a Modo crash report.
NOTE: In the commands written below, replace the <username> field with your username (for example: /Users/Smith/Desktop/).
Open the Command Prompt and run the following command:
"C:\Program Files\Luxology\modo\11.0v3\modo.exe" -dbon:qt -dbon:ogl -dbon:gnz -dbon:agl -dblog:C:\Users\<username>\Desktop\modoLog.txt
Open Terminal and run the following command:
/Applications/Modo11.0v3.app/Contents/MacOS/modo -dbon:qt -dbon:ogl -dbon:gnz -dbon:agl -dblog:/Users/<username>/Desktop/modoLog.txt
Open a Terminal session and run the following command:
/usr/local/Modo11.0v3/Modo11.0v3 -dbon:qt -dbon:ogl -dbon:gnz -dbon:agl -dblog:$HOME/Desktop/modoLog.txt
NOTE: The examples below use the default installation paths for Modo 11.0v3. If you have a custom installation path, you will need to update the command including the correct location. If you are using a different version of Modo, replace all instances of '11.0v3' with the exact version you are using.
After launching Modo with these flags enabled, please continue to use Modo until the crash occurs. Once this happens, please open a Support ticket and send us the 'modoLog.txt' file generated together with the following information:
- Your system spec including graphics card and driver version
- Step by step instructions on how you are reproducing the crash
- The example .lxo file that you can reliably reproduce the problem with
