You can check out this program here https://github.com/fizzy81/animated-models. Check youtube for some good tutorials on how it works. Not sure if that's exactly what your looking for.

Makes sense. I tried it with stained glass but ended up with this nonsense. Sorry if this is a noob error, I'm fairly new to modeling for minecraft.

Have this really weird issue going on with a model I made. I'm replacing jungle leaves, and for some reason when I place them down the transparent texture is just solid black, but when I place it on an armor stand head it renders just fine. Any help would be appreciated.
