BSP Compile Log

Last Updated Aug 8, 2014

Every time you compile your level, the Valve compile tools (VBSP, VVIS and VRAD) will log information, notices and errors into a log file. By default, this file is located in the directory of your VMFs and matches the name of your level with an extension of ".log".

Each time you compile your level, the current compilation information is appended to that log file.

You can open this file in Wall Worm via these two methods (added in WW 2.17):

  • VMF Exporter UI: Log Button
  • Menu: Wall Worm > Wall Worm Level Design > Wall Worm Map Compile Tools > Open BSP Compile Log

Last Compile Log

When you export a VMF from Wall Worm and do not use the Output Compile Window option, Wall Worm will output the compile results into a separate log file that only contains the current compile results. This file is located in the same directory as the standard log file but is named in this format: thelevelname_last_compile.log.

Using the Compile Log

You can use the compile log to troubleshoot problems with your level, such as finding leaks, brush IDs of objects with duplicate planes and more.

You can use the Interlopers Error List and Error Checker to understand more about errors and notices.
