Changes

During the development process, 3D models contain a good deal of information needed by the artist every time they save or load the model. When the model is finished, it is often exported and broken up into smaller files with many unneeded attributes striped from them. When the models for FF7 were created, they were exported into Psy-Q's 3D library formats. These include [[PSX/RSD|resource data (.RSD) files]], polygon data (.PLY), polygon groups (.GRP), materials (.MAT), [[PSX/TIM_file|textures (.TIM)]], [[PSX/HRC|skeletal hierarchy (.HRC)]], and animation (.ANM).

The models are handled differently between modules. The models in the "battle" modules have a different animation system than the field models. When the models were converted to the PC version, they were taken from Psy-Q to a more PC-friendly format, some are even the original, uncompiled, Psy-Q files.

The PC models are stored in the LGP files in the /DATA directory. The names for the models were obfuscated a little, but can be recovered via the plain text [[FF7PSX/HRC|Hierarchy files (.HRC)]], [[FF7PSX/RSD|Resource data files (.RSD)]], and [[FF7/P|Polygon files (.P)]].
