Connected Textures don't work with BadLion Client

[hndrk97]

Hey there!

This is a rather specific situation, but maybe someone can help me out. I'm playing Minecraft 1.20.4 with the BadLion Client and activated Optifine. I use the PureBDCraft resource pack and also the connected textures add-on. Connected textures are also activated in the quality options. I also use some other add on packs, which work just fine.
When launching Minecraft with the Mojang Launcher, the connected textures work. But not with BLC. Has anyone any idea, what causes this and if there's a way to get around this issue?
