FYI, there are some changes in the 3.3.3 patch that require changes to Mapster to work right. I just patched it up (though not sure what I did is right) on the PTR, so if 3.3.3 goes live tomorrow, I will test it further, and update here (and open a ticket)..
Fogclear is still broken in 1.3.11-3-g83dc93b. The overlay shows, but the fog underneath is not cleared. I tested this on a new gnome character, and uncovering jigsaw pieces of the map did not make the rest of it appear.
Yes the overlay part works fine. But the fog is never cleared in the first place.
The way I remember it working before was that the fogclear module removed ALL the fog from the entire map, revealing it entirely, then the overlay sat on top of the fully cleared map, showing the player where they hadn't yet explored.
I have 2 screenshots. The first shows the map with the overlay set to 100% transparent. All the parchment colored areas should be fully uncovered, showing Ironforge, the lake to the east side of the zone, etc. The second shows it with the overlay set to 20% opaque. That pink mask should be covering a the map with no fog visible.
Edit: After creating a new profile, I think I understand how it works now. The fogclear opacity controls not just the fog overlay but the "clear" map portions themselves. Since I had it at low opacity, I couldn't see the map beneath it. The new profile with the color set to pure white and 100% opaque made that obvious. The trick is not to use the opacity function at all, and treat the darkness of the color as "opacity", since it only impacts the fogclear.
Thanks for the updates to Mapster to keep it current.
I'm getting this error now, since patch 4.1, that prevents placing the raid markers on the ground. This can be tested by going into a raid, pulling out the pop-out from the right of the screen, and trying to place a raid marker.
