So I downloaded a texture pack https://www.planetminecraft.com/texture_pack/mickey-joe-s-relatively-improved-default/ that modifies some animals, the thing is that only loads the modified entities with Optifine, as it seems the Optifine feature Custom Entities is needed for this texture pack, I wanted to ask if there is another way to load this modified entities without Optifine because i have a problem with Optifine and it gives me huge lag spikes so I use Better FPS Mod instead and that I really want to use this texture pack
