Hi,

A user of my resource pack encountered an issue with overlays when used alongside Overlay’s by Kany. After investigating, I found that when two packs are active simultaneously, overlays from both are enabled, rather than just the one on top.

To illustrate this, I created two test packs (resourcepacks.zip):

In this example, one pack applies connected textures to dirt (affecting diorite), while the other affects grass blocks. As shown, the dirt connects to both, which can lead to conflicts when multiple packs have similar behaviors.

For testing, I used a minimal setup with just these two packs and the latest version of Continuity on Fabric (via Modrinth Launcher). The user who reported the issue was on Forge and shared their config in the linked issue. I’ve also observed the same behavior with OptiFine and noticed a similar report in #343.

Thanks for taking a look!

This is intended and is just how that format works.
