What is a GRN file?

GRN files mostly belong to Granny 3D by RAD. GRN is a 3D graphics filename extension for 3D models created with Granny 3D, a toolkit for creating 3D models, games, and animations on Windows and Mac computers. The GRN file typically contains animations, surfaces, textures, blend graphs, and events. An outdated use case of the GRN filename extension is with Masterpoint, an online platform that stores bridge games, clubs, and player names of Australian Bridge players in GRN files.
