PortalMod: Expanded
PortalMod: Expanded adds Portal-inspired test chambers, blocks and elements to Forge 1.16.5, drawing on the Portal 1 and Portal 2 series.
What it does
The mod expands the selection of PortalMod content with blocks and test elements that were not in the original. Its Arbor section adds nine overgrown variants of Portal 2 testing parts, from buttons and cube droppers to a chamber door, all modeled on the originals. Its Erosion section adds Portal 1 style test chambers and elements, including a lunecast blackplate and an Autoportal.
The mod is aimed at builders and players who want the testing-chamber aesthetic in their worlds, and its stated goal is to fill in features missing from PortalMod. Installation needs Forge for Minecraft 1.16.5 and the original PortalMod. Both the server and every player need the mod, since the environment is client and server. The code is open source under the GNU General Public License v3.0 only, with a public source code repository and issue tracker.
