Hi! I did some research and thought I downloaded everything I needed in order for Continuity to work. Here's my full list of mods:(including the Fabric Installer)

fabric-api-0.43.1+1.18
iris-mc1.18.1-1.2.0-pre
lambdynamiclights-2.1.0+1.17
modmenu-3.0.1
okzoomer-5.0.0-beta.3+1.17.1
replaymod-1.18.1-2.6.3
sodium-fabric-mc1.18.1-0.4.0-alpha6+build.14
continuity-1.0.3+1.18
indium-1.0.2-alpha2+mc1.18.1
(Resource Pack: Better+Leaves+Add-on+V2.7-1.18)

But when I load into my world and place glass blocks or panes they still aren't smoothed/connected. I've tried turning "Disable CTM" and "Use Manual Culling" both On and Off but it had no effect. Could you please help?

Thank you!

Did you load the built in resource pack called "default" with the connected textures?

Ah! I hadn't realized that this was treated like a resource pack. I've always run on OptiFine, so setting up Fabric mods/textures in new to me.
I've loaded them both and I worked great!

Thanks so much, I really appreciate it! :)

No problem!
