I just did a quick test with mineral walls, works without fail.
I just copied my overrides for them and made one for microcline:
[OVERRIDE:131:T:MineralWall:_MDF_overrides_2:R:16:48:49:50:51:52:53:54:55:56:57:58:59:60:61:62:63::::INORGANIC:MICROCLINE]
[OVERRIDE:132:T:MineralWall:_MDF_overrides_2:R:16:48:49:50:51:52:53:54:55:56:57:58:59:60:61:62:63::::INORGANIC:MICROCLINE]
[OVERRIDE:133:T:MineralWall:_MDF_overrides_2:R:16:48:49:50:51:52:53:54:55:56:57:58:59:60:61:62:63::::INORGANIC:MICROCLINE]
[OVERRIDE:134:T:MineralWall:_MDF_overrides_2:R:16:128:129:130:131:132:133:134:135:136:137:138:139:140:141:142:143::::INORGANIC:MICROCLINE]
TreeTwigs etc work too.
[OVERRIDE:24:T:TreeBranches:_MDF_overrides_10:24:::::PEAR] pear
[OVERRIDE:24:T:TreeBranchesSmooth:_MDF_overrides_10:24:::::PEAR]
[OVERRIDE:24:T:TreeTwigs:_MDF_overrides_10:24:::::PEAR]
Okay, so.
This works for me:
[OVERRIDE:170:T:StoneWall:_10:16:::::MAGNETITE]
[OVERRIDE:157:T:MineralWall:_10:17:::::TETRAHEDRITE]
[OVERRIDE:157:T:StoneWall:_10:17:::::TETRAHEDRITE]
Tested it ingame and it shows up as unique tiles
EDIT: The above overrides did not work as they work essentially the same as:
[OVERRIDE:170:T:StoneWall:_10:16]
[OVERRIDE:157:T:MineralWall:_10:17]
[OVERRIDE:157:T:StoneWall:_10:17]
Could it be that I am using a MAC version of TWBT 6.61 that we have different results?
This does not work for me:
[OVERRIDE:170:T:StoneWall:_10:16::::INORGANIC:MAGNETITE]
[OVERRIDE:171:T:MineralWall:_10:80:::::RAW_ADAMANTINE]
[OVERRIDE:171:T:StoneWall:_10:80:::::RAW_ADAMANTINE]
Why Raw Adamantine does not get assigned a new tile really puzzles me. Is it actually FeatureWall?
With the twig overrides. The problem seem to be that underground twigs and branches don't have a material. so hence :PLANT: or :PLANT_MAT: will not work. Hence use only :FUNGIWOOD:/:SPORE_TREE:
