Mods I can suggest,

• Extra Pieces (Blocks, Slopes, Good stuff like that)
• Adorn (Furniture, Good stuff here too)
• More Layers (Leaf Piles)
• Fabriblocks (Bookshelf's?)
• Tree Bark (Obvious reasons) Tree Bark is not open source, for this reason I will not support it. Ask MarioAndWeegee3 to add the necessary integration on his side.
• Tool builder (Makes tools completely customizable!) Tool Builder is not open source, it will not be supported. Use Materialisation instead. Also, there's nothing really to add here anyways.

Might come back and suggest more! :)

Will look into these 👍

Extra Pieces: You can place this file in config/extrapieces/piecepacks for compatibility at the moment. Future versions of Terrestria will ship with it once @Shnupbups adds support for loading piecepacks from mod jars in Extra Pieces.

Fabriblocks blocks to be added:

• Bookshelves per wood type

• Leaf Piles (maybe multiple layers like More Layers)

• Lecterns per wood type

• Basalt Tiling, Walls, Buttons, Pressure Plates, etc?

I cannot guarantee support for More Layers, Tree Bark, or Tool Builder. They are not open source mods, meaning it is not safe for me to inspect their source code or decompiled output.

I can do Materialisation support in the future, but does this mod add any new materials?

Just wood and stone types.

Then there is basically nothing to add, I use all wood types as 1 wood material, same with stone

Unless you consider basalt a tool material, I do not think there is anything to add for Materialisation or Tool Builder.

Extra Pieces is supported by default in 1.0.5

Adorn 1.3.0+ has support for Terrestria.

Continued in #60.
