Alright, I've finished migrating my merged install in SFP1 to the new WOE patch as a big merged hybrid install like FC.
Essentially everything works, but I'm noticing some inconsistent anomalies.
Some addon terrains I'm exploding on runway, I'm sure ini edits can fix that shortly. Mostly in older terrains like the southwestern US terrain or the likes.
Migrating green hell over worked just fine, but the tileset + trees for GermanyCE are a bit off. The Trees all seem to have squarish borders on some sides, as if the TGA was upside down or the uvw mapping was screwed up.
Some effects like certain afterburners aren't showing up.
Also, inexplicably, some aircraft textures simply aren't displaying, like on the F-15E, solid white. The nozzle and decal textures work, but not the main ones. (resolution came to mind, but I set things to unlimited but no change)
