Mundial Mons Reani Pack updates older Cobblemon creatures with fresh movements and changes the 3D models of several existing monsters. If creatures in your world still use their older appearances or lack updated animations, you need to adjust your active pack order so the new visuals take priority.
Adjusting Resource Pack Order
1. Press Esc while in your world, select Options, and click Resource Packs.
2. Check the Selected column on the right side of the screen.
3. Hover over Mundial Mons Reani Pack and click the up arrow on its icon until it sits above the main Cobblemon pack and any other creature packs.
4. Click Done to reload client assets. If models or movements fail to update during play, press F3 + T to force Minecraft to reload all active models and animations.
Verifying World Spawns
Visual remodels load through resource assets, while newly added monsters require the data pack to run in your world save. Open chat and enter /datapack list (with cheats enabled) to check whether Mundial Mons Reani Pack is active. If it appears under available packs rather than enabled packs, run /datapack enable with the pack's listed name or move it into the active column from the world's Data Packs screen so the new creature lines begin spawning in the wild.
