What is an RTTEX file?
An RTTEX file is a texture file saved in the Robinson Technologies Texture (RTTEX) format. It is used by Growtopia, a game that allows you to build worlds, compose music, choose an occupation, trade items, and earn achievements. RTTEX files store one or more textures for gameplay elements, such as characters, items, and landscape.
The RTTEX format is a container that supports various image types including JPEG and PVRTC. It may be compressed using zlib.
