Hello!
DunGen can now generate Automatic Line of Sight Definitions for Fantasy Grounds Unity.
It is a very simple process as seen in the video, but downloading at higher resolutions or maps that have an odd number of tiles can require just a tiny amount of extra manual work since FGU doesn't let me automatically set some values. That is manually setting the tile size and slightly offsetting the grid in some cases [instructions in the F.A.Q.].
I have talked to SmiteWorks devs and they will eventually add support for those features, so I'll update the app and that'll be done automatically by DunGen once it's available. They're cool like that!
If you have any questions or something doesn't work, please let me know so I can fix it or add it to the F.A.Q. if necessary.
Cheers!
