by snk07

Block of Sky Unofficial Port brings the sky dimension and the End Gateway effect into blocks that players can place and control with redstone.

FabricClient and serverGNU Lesser General Public License v3.0 onlyOpen source1.21 – 1.21.1

What it does

Block Sky and Block Void are the two blocks of the mod. Block Sky renders the sky dimension on its faces, and Block Void renders the End Gateway effect. Both can be switched by redstone signals, so a player can build contraptions that show or hide these effects on demand.

The mod runs on Fabric for 1.21 and 1.21.1, and each side must run it because it is a client and server mod. Architectury API and Fabric API are required, and Sodium is optional. Shaders are not supported, the same limit as the original mod. The code is open source under the GNU Lesser General Public License v3.0 only, and the source is available publicly.

Key features

  1. Sky rendering block

    Block Sky shows the sky dimension on its surface, so a build can display a sky view inside a room.

  2. End Gateway block

    Block Void reproduces the End Gateway effect, which lets a builder place the look of a portal anywhere.

  3. Redstone control

    Both blocks respond to redstone, so a circuit can turn each effect on or off.

  4. No shader support

    Shaders do not render these effects, matching the original mod, so players should not expect shader packs to apply.
