FGD Parser Problems
The FGD parser in the free version of WW has some known issues:
- The parser sometimes has a "Unknown System Exception" error.
- The parser can be very slow.
- The parser does not work in 3ds Max 2017.
At this time, there are no plans on addressing these issues in the FGD parser for the free version of WW. If you need to use entities in Max 2017+ or have the issues above, you should upgrade to Wall Worm Pro which uses a fast and reliable parser.
