I can’t find my book mark for the Arkham rooftop snow talk OR the naughtydog sand footprints.
But it got me thinking; it would be cool to have a thread for footprints in/on stuff.
The Arkham talk was awesome because they used a camera to create a projection for particles to render to a target that created the displacement map for the snow.
The sand was awesome because they showed some very nice normal map techniques.
But footprints are a magnificently crenulated feature for any game.
