[1.11.2] Animating rotation of json model in a FastTESR

[mennovf]

Hi.

 

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 = this.getWorld().getBlockState(pos);

        Matrix4f rot = new Matrix4f();
        rot.setIdentity();
        rot.rotY((float)(Math.PI * 3 / 5));
        vertexbuffer.setTranslation(x - pos.getX(), y - pos.getY() + bounceHeight, z - pos.getZ());
        IBakedModel model = questionmark.bake(new TRSRTransformation(rot), DefaultVertexFormats.BLOCK, ModelLoader.defaultTextureGetter());
        blockModelRenderer.renderModel(this.getWorld(), model, state, pos, vertexbuffer, true);

 

And a picture of what it looks like is included. The marked parts are where the faces of the boxes disconnect after the transformation.

Might be relevant: angles that are a multiple of Pi/2 bake correctly.
