All,

This screenshot is from Gettysburg. The hotspot is on Buford and some arty in (67,141). Playing hot seat with just regular FOW and currently "show visible hexes" is selected. As can be seen I can see the entire road between the reb regiment and the leader that is circled in the screenshot. That road is lined back to back with reb regiments. Why can I not see the regiments even though the hexes are highlighted? They are all at the same elevation as the visible leader and regiment. The hexes in the row to the right of the units that I know are there are greyed out because the "invisible" units are blocking the LOS to those hexes. Is this a bug? Thanks in advance.

Interesting situation. I suspect that the situation you have shown highlights a limitation in the WDS LOS algorithm. My guess, and it is only a guess, is that WDS does a check between the center of hexes. If the path between the center of the observers hex and hex that is trying to be viewed passes through any part of a hex that blocks the LOS, the hex that is trying to be viewed is also completely blocked. In your situation, the first Confederate unit in the column of units along the Pike is not blocked, so it is visible. Each successive unit behind it is blocked by a unit in front of it, even if the unit in front of it is not visible, so none of the regiments behind the first are seen. In real life, we would see part of each unit along the Pike behind the first unit and be able to infer that there are complete regiments marching along the road in column.

As an experiment, I took something similar to the situation that was shown and moved every other CSA unit off the road to the NE. I added yellow lines to illustrate LOS. Most of the CSA units are still hidden, but one did appear. Note the last unit in the marching column is still not visible.

Wallace,

Thank you for joining the discussion. I would be VERY interested to see the Union POV screenshot with the V key "visible hexes" on and see what hexes are highlighted. Thanks.
