Continuity mod (1.19.2, 1.8.2) is a Fabric Mod built around modern APIs in order to provide the best connected textures experience. It provides full Optifine parity to all resource packs that use the /MCPatcher format.
Continuity is dependent on the Fabric. It is client-side only. The mod comes with two resource packs. One provides default connected textures similar to Optifine and the other fixes glass pane culling. If Sodium is installed, continuity will not work.
