what version of forge are you using?

as for the grass showing as dirt will check that out 2.
I can't understand this S:
I've been searching and MapWriterBlockColours.txt 'dirt' and 'grass' has got the same value (ff866043) but in version 2.2.5 grass has a correct value (ff9b9b9b). Maybe some code error or whatever on src/main/java/mapwriter/BlockColourGen.java

i think i have to find a other way to get the block colours becous it seems that using the icons ingame fails.

maybe i can get the uv info from the jsons or something, but i'm still finding out how minecraft works on that part now

confirmed for 11.14.3.1519 and 11.14.3.1521 on Multiplayer map

could you try with the recomended forge version?

On recommended forge version and 2.2.10 nether bugs dissapear but... Grass seems like dirt?

Also, in multiplayer map

oke, something probably changed in latest forge version, i will check this out when i have my enviorment working again with the latest forge,

as for the grass showing as dirt will check that out 2.

this should be fixed in the new version.

will leave this open for now, dont know if it also fixes the grass bug

Nether bug fixed, grass; leaves etc. still bugged on 11.14.3.1450

I'll keep testing

did you try deleting the old color files so the game regens them?

i'm unable to reproduce the dirt bug....

Okey.... I'll try with Forge 1.8 - 11.14.4.1563, MapWriter 2.2.11 and I deleted /config folder... Now works fine. It seems that was my mistake. Sorry for the inconvenience! :)
