Abstract: The specification relates to the generation of in-game animation data and the evaluation of in-game animations. According to a first aspect of this specification, there is described a computer implemented method comprising: inputting, into an encoder neural network, input data comprising a plurality of input pose parameters indicative of one or more poses of an in-game object in an animation; generating, by the encoder neural network, one or more encoded representations of the one or more poses of the in-game object from the input data; and determining a quality score for a pose of the one or more poses of an in-game object based on the one or more encoded representations.
