ZRS is the model format used by Z2's engine. ZRS file contains information about many 3D models, including information about Mesh, Texture, Material, Dummy, Spinner, animator, etc.
This program can read a number of 3D elements from a file into the cache. The cached data is then converted into a file in 3DSMAX format. The current output file format is an Obj file.
More functions can be added later, such as reading texture files, animate files, sound files and converting to different 3D file formats.
