Make your Galacticraft experience more seamless with connected textures for Air Locks as well as Galacticraft's Copper, Tin, Aluminium, Titanium and Lead Blocks.
All of the blocks that look similar to Tin Wall Blocks have been given a connected texture overhaul too. These include Tin Wall Block Slabs, Stairs and Walls, the tops and bottoms of Tin Decoration Blocks, Slabs, Stairs and Walls, Sealable Pipes and Cables and most importantly Hidden Redstone Wires and Repeaters (your secret is safe with me).

The Connected Textures for Galacticraft resource pack was initially created for use in my First Mole on the Moon modpack.
You might also be interested in my Space Age resource pack, which makes blocks from other mods fit with the Galacticraft style.
The ConnectedTexturesMod (CTM) is required for this resource pack to work.
Let me know if you would find a version that uses Optifine instead of CTM useful and I might make one.
