Regarding your SEAURBAN tiles - could you post some manual about their proper placement in relation to each other? They're great but I thought there's no point in wating time to figure out this 9-piece puzzle by myself. I don't know if this post belongs here but the thread about the terrain pack was deleted, and you're the author, so.
I actually did take a look at the original files from TFTD, to figure out the proper placements and patterns. Took a while but i had time on christmas.
Example (Numbers are MCD Index numbers for the SEAURBAN.MCD)
PORTUFO02 uses the following pattern:
11 | 5 | 8
13 | 4 | 9
10 | 3 | 6
11 | 14 | 17 <-- Pier Shadow
13 | 16 | 18 <-- Pier
10 | 12 | 15 <-- Pier
11 | 5 | 8
13 | 7 | 9
Repeating Patterns on PORTUFO03, PORTUFO04, PORTUFO05, PORTUFO06, PORTUFO08, PORTUFO09:
10 | 3 | 6
11 | 5 | 8
13 | 7 | 9
10 | 3 | 6
11 | 5 | 8
13 | 7 | 9
10 | 3 | 6
11 | 5 | 8
Repeating Pattern on PORTUFO07, and the Cargoship and Linership Maps.
1 | 3 | 6 | 1 | 3 | 6
2 | 5 | 8 | 2 | 5 | 8
4 | 7 | 9 | 4 | 7 | 9
I hope this gives you some clue :>
