I've noticed that the connected textures mod doesn't seem to apply to AE2's facade feature (In the example where I found this out I was using mekanism plastic blocks).

I think adding this to somehow work with facades would be a great addition to the mod.

AE2 dev here. This can be solved if CTM uses MinecraftForge/MinecraftForge#9066, which is more or less a Forge replacement for IFacade.

After further experimentation, I realized the facades connect with each other like how ctm works, but not with the real blocks
