Fence On Slab!
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Finally Fix Fences Floating on Slabs!
Works with Every Fence Type!
Keep Those Animals in with Fences on Slabs!
Troubleshooting
Sometimes NeoForge/Forge/Fabric misorders mod and vanilla resource packs, since this adds to the minecraft resource pack it has to be added later
If your fences look like the image below, make sure to fix your resource pack order!
Vanilla Compatability
You can uninstall this mod, and fences will just appear above the slabs, and if you reinstall the mod later it will be put back on the slab. Complete Vanilla Compatibility if you decide to remove the mod.
