  Neural Style Transfer (NST) research has been applied to images, videos, 3D
meshes and radiance fields, but its application to 3D computer games remains
relatively unexplored. Whilst image and video NST systems can be used as a
post-processing effect for a computer game, this results in undesired artefacts
and diminished post-processing effects. Here, we present an approach for
injecting depth-aware NST as part of the 3D rendering pipeline. Qualitative and
quantitative experiments are used to validate our in-game stylisation
framework. We demonstrate temporally consistent results of artistically
stylised game scenes, outperforming state-of-the-art image and video NST
methods.
