Do Smooth keyframes in blockbench work while using the geckolib plugin?

Hey guys I'm a bit of a newbie here, I've used Mcreator for sometime while using Nerdy's GeckoLib Plugin and my models/animations in Blockbench all use smooth keyframes and they actually work even after exporting them to Mcreator, all my mobs would show up in the world with the animations all smooth and working fine, but now for some reason all my smooth animations turn linear in the minecraft world, it's like mcreator doesn't support smooth animations anymore... Does anyone here has a solution or a suggestion, am I doing something wrong?
