[TERRAIN] Help with custom LM terrain

[SuedecivIII]

Hey, I'm trying to integrate custom LM terrain into my mod. Most of the terrain is from MasterOfMyrrorCiv3. Only, when I import it into my mod, it creates an odd shadow on terrain adjacent to the LM terrain (the chasms you see below, it's supposed to be like a maze)

I'm not intending to use all their assets, but this is what it looks like with all of them enabled.

Any idea what might cause these shadows, and how to fix them?

So basically, this is caused by the way Civ3 draws "base" terrain (grasslands/plains/deserts/tundra/coasts/seas/oceans); instead of drawing each tile, tile-by-tile, it actually takes them together and draws them corner-to-corner based on what tiles they are adjacent to in order to create terrain blending, if that makes sense. So a grassland with a desert nw/n/ne will have the top corner of its tile (and the east/south/west corners of their tiles, respectively), taken from a particular tile in the xdgp.pcx set.

Unfortunately, landmark base terrain has no files where it "blend" with regular terrain, the terrain assumes either it's all landmark or all regular.

So what you're seeing here is the game placing a mixmatch of LM base terrain tiles and regular base terrain tiles; one set is darker, the other lighter.

The best way to deal with it is to delete the ones which are the "wrong" shade and copy and rename the ones with the correct shade.

The files you'll want to look at are, for Landmark terrain:
lwcso.pcx, lwooo.pcx, lwsss.pcx, lxdgc.pcx, lxdgp.pcx, lxdpc.pcx, lxggc.pcx, lxpgc.pcx

For Regular terrain:
wcso.pcx, wooo.pcx, wsss.pcx, xdgc.pcx, xdgp.pcx, xdpc.pcx, xggc.pcx, xpgc.pcx

As you can see, the landmark base terrain just has that extra l in front.

Perfect! You're a lifesaver, thank you
