I was told by a DCS expert that ED f**ked up all the old building models on the terrain (for 5 years, since FC2, probably intentionally) that's why you have hard times (Dimitriov, CrazyEddie, Starway etc.) with those LODs and textures on the block_texture.dds and that's why we can't use Mustang's more detailed FC2 textures in DCSW for the (almost) same building models.
(If this failure happened accidentally that's a bigger shame IMHO)
If you check buildings in FC2 you will see there are more detailed models on the terrain, more trees in the cities and more forests on the hills/mountains.
There are huge problems, mistakes and mess in the current DCSW terrain files. ED stepped one backwards with DCS-Warthog, so now we are at Flanker2 or LOMAC level (10 years lag) with the terrain on the Black Sea map of DCSW.
ED sometimes spoil things to others instead of do fixes well, what need few minutes work only.
I hope we will get correct fixes and improvements with the 1.5 patch for the Black Sea map.
