Kopfdorfer,
Indeed, I'm purely an offliner. Over the years I've played a number of campaigns, scripted and dynamic. And I'm fully aware of the effect of the removal of bridges. I knew from the outset that incorporating proper terrain would bugger that aspect, rendering this iteration as incompatible with campaigns that involve bridges in any capacity.
I also realize that discussing this update in the context of the stock base map should be clearly qualified, making unambiguous that this one is in no way a complete replacement. It's aimed more at those who would use it to create their own missions. I'm striving to keep things to a near minimum in terms of object population, along the lines of the original, principally for better frame rates--and to leave room for player creativity. This would be another stand-alone map in its own right. Of course, if one had no reason to retain the stock map due to never playing campaigns, this one could replace it.
I love the Green Hell map, but the latest iteration having the westward extension has boosted the object density significantly in a number of areas. The worst is the airfield complex at Port Moresby, where frame rates on my reasonably capable computer drop to as low as 4 fps in certain view directions. This inspired me to make up a better version of the stock map for early '42 action on a 1:1 scale battlefield. (The PNG map, while otherwise great, is half scale, and Mr. Oblongo's Kokoda map has more limited coverage.) If others can make similar use of this updated stock map, so much the better!
Given the already loss of compatibility with campaigns, this opens up the whole shebang for improvement. Such as relocating some fields, and of course 'de-modernizing' strips to simpler arrangements. And re-routing some roads due to the terrain changes.
I've already greatly reduced in areal extent what was a sprawling megalopolis at Moresby.
Before going totally nuts I'll release an interim version that will incorporate the main improvements.
