Abstract: The subject technology receives an online request from a first player to enter a game via a network. The subject technology determines a set of interoperable skill metrics of the first player, each interoperable skill metric corresponding to a different skill metric. The subject technology selects a particular interoperable metric from the set of interoperable skill metrics based on an analysis of prior game data of the game and an indication of a predictive performance of each interoperable skill metric. The subject technology performs a skill-based matchmaking process to match the first player to at least a second player based at least in part on the selected particular interoperable metric. The subject technology initiates an instance of the game for the first player and the second player.

Abstract: Techniques for configuring hair for animation include obtaining a first representation of a set of hairs on a surface and a second representation of a subset of the hairs. At a vertex of the surface, an interpolated hair is generated by minimizing a difference between a shape of a first hair and the interpolated hair. An edit is received to modify the shape of the first hair. At the vertex, a modified interpolated hair is generated by minimizing the difference between the modified hair shape and the modified interpolated hair. The interpolated hair and the modified interpolated hair are projected onto a root of a second hair. Rotation parameters indicating a rotation and a scaling factor indicating a scale difference between the projected interpolated hair and the projected modified interpolated hair are computed. The rotation parameters and scaling factor are applied to the second hair to propagate the edit.
