Thanks EH!!!
I basically discarded the map I began last fall and started over from scratch about two months ago. This was mainly a result of me having learned so much more about the editor and level design in the intervening year. Rather than trying to turn a sow's ear into a silk purse, I thought it best (and quickest) to just reinvent the scenario.
I would consider the map about 80% complete at this point. Aside from minor tweaks that will likely be needed at the end, the terrain and its layers are more or less in their completed form. The objectives are layed out - but I need to get them to trigger correctly. The play area will be 1km north to south, by 2km west to east, which is quite smaller than the original version. The layout is based on a combo of Google satellite imagery and 1950's Soviet topo maps of the area. I've also used personal photos of the area as reference in laying out the terrain, so this should be an authentic experience from that point of view. Luckily, the real terrain in that region of Russia consists of rolling hills and occasional heights (like Orel), therefore placement of AP's wasn't too hard to pull off.
Still plenty of things to do: insert remaining art assets like buildings, rail and power lines, interior decoration for the few enterable buildings, environmental stuff like vegetation and water, to name just a few.
The scenario hasn't changed much: As in RL, the spearhead of the German attack is lead by the GD division, supported by its own StuG battalion and Pz III's of the 24th Panzer division .The objective is to seize keypoints on the approach to Voronezh, including the key bridges over the Don River at Semiluki. The battle ends in the suburbs of the city itself (athough you don't actually enter the city completely). The Germans need to rely on speed and coordination to win. The Russians need to use their numbers, the terrain, and the long distances to their advantage to run out the clock.
Divinehammer and a few others are helping out with art assets and other things. Definitely props!
I'll post some screenies this weekend depending on progress. All you'd see right now is layered terrain with cornfields and roads.
