I can explain the lighting, the game seemed to find the map blanked out so I thought it was that it was too dark so I rased the lighting. Soon the players buildings were very bright and the map had either water missing or the grass was gone so I found if I rased the level parts began to apper and others gone so after many tweeks I gave up.
I've got marble madness but I didn't find any cliff errors, though concerning the shores I cound be botherd being accurite so... yea the shores errors are my fault.
The cliffs were straight because if I tried to make them more natural (pointy and whatever) they would be just eye candy (it would make no difference).
The slope in the north of the French (veinhole) side was done on purpuse, besides, dont slopes overlap cliffs in mud slides and whatnot?
The game IE comes when, on the loading screen, the small texts on the side get to "Secondery scan of combat zone" it sais there is an IE. It doesn't happen now because I put in the values for lighting.
I never knew about the visable area thing... I used the change map because a players tiberium pach was outside te blue line so I incresed the size.
For anything I might of missed the answer is either I don't know or yea whatever.
BTW, do not worry about the paragraph after paragraph of text, I can read you know!
