About this Mod

Starlight reloaded

Mod for rewriting the light engine to fix lighting performance and lighting errors.

The StarLight Reloaded mod is an unofficial port of the StarLight mod by the author spottedleaf.

Compatibility

Starlight can be installed either on the dedicated server or client. It is not required to be installed on both sides. If you have Starlight on the server, clients can use Vanilla/Phosphor/Starlight to connect. Likewise, if you have Starlight on the client, you can connect to Vanilla/Phosphor/Starlight servers.

Starlight cannot be installed with Phosphor, they are completely incompatible. Browsing through Starlight's Issue Tracker will show further mod incompatibilities. Starlight is a rather destructive light engine rewrite, so it should be expected to break mods more often.
