PsiTweaker
by GDavid
PsiTweaker lets server owners and players adjust parts of the Psi addon through configuration, with no default behavior changed until a setting is edited.
What it does
Psi must be installed alongside PsiTweaker, since it is the required dependency. The addon exposes some of its behavior as configurable options, and until those options are changed the Psi content plays as it does by default. The mod is published for Forge only, across nine release versions 1.19.2 – 1.20.6, with 1.20-1.0.1 as the latest file. Client and server must both have it, with matching configurations, and the project is open source under the GNU Lesser General Public License v3.0 only.
Key features
Configurable Psi addon
Several values in the Psi addon can be changed, such as options that were fixed in the base content.
Defaults left intact
Nothing is altered until a configuration value is edited, so the untouched game behaves as before.
Matching configurations
Client and server configs should match so that all players see the same Psi behavior on the server.
