Whenever I try to spawn something from Mo' Creatures I get a shadow and noise. I can still interact with them, but they're invisible. These are the mods i'm using
Mo' Creatures, DecoCraft, Exotic Birds, Ore Sheep, Adventure backpacks, Doggy Talents, Wings,Horns And Hooves, Doggy Talents, Pam's Harvest Craft, Storage Drawers, Biomes O' Plenty, Custom NPCs, and Journey map
I tried re downloading it but I still got the same thing.
I just had this problem too.
When downloading mods you should make sure they have a partner mod.
Example being morph mod, for it to work you need ichunutil.
To cut to the chase you need to download custommobspawner
This has all the versions. Enjoy c:
