Important information
Biome blend is supported for the biome Rainfall Ridges and working for the Wisting biome. For optimal experience, set it to an value between 5x5 and 8x8.
For an optimal experience, turn smooth lightning on.
Rainfall Ridges
This is a small biome, often near taigas. It's relatively flat.
Marshland
This biome was a swamp ages ago. But then it dried. Here you can find frogs and sometimes slimes.
Wisting Wood
This is the new wood type. It is completely coloured green. With this wood you can craft all things you can craft with other things (currently not all things have an own version for this wood).
Aluminium
Aluminium is the new ore in this mod. It's at the same level as iron (gives you a bit more protection but deals a bit less damage). It generates between height -24 and 38, average of 8 groups per chunk with an average of 5 ores per group.
Performance Issues?
The mod shouldn't impact the performance of Minecraft. Also the Alpha-Versions are (unexpectedly) very stable, except you use the "Ampflified" world-settings when you create a new world.
Graphics
This is a mod currently in the Beta-phase. Because of that the main emphasis currently lies on programming and fixing bugs and not on providing nice graphics. You can expect graphic updates in the future in Beta-phase and after the first Release-version.
Questions, Bug Reports?
Ask/report on the intern issue tracker.
Known Bugs
We know about a bug where in some scenarios the leaves fall from the wisting trees. We are trying hard to fix it. Fixed.
We know about abug where sometimes two Wisting trees generate on top of each other. We are trying hard to fix it.
Special thanks to Northoff for helping me with the graphics and the name of 'Rainfall Ridges'!
