I have a model which is separated into two json files, one is static and the other one is animated. I'm having trouble with the animation (which is just a rotation around the y-axis in this case). The approach I'm using now is to animate it by providing a TRSRTransformation with a Matrix4f which represents the rotation. The animation kind of works bit the individual elements of the json file are distorted, as if their faces are animated separately but wrong.
The code of the renderTileEntityFast:
final BlockPos pos = te.getPos();
final IBlockState state
