EvilEngine/JSP
JSP is an asset type which defines a 3D model. It's a RenderWare binary stream file. There are two types of JSP: the normal (model) has a format much similar to a DFF. They can be opened by RWAnalyze and other tools that work with RenderWare models. GTAModding has a lot of useful information regarding this format. The other format is used for collision data and is very different from a normal JSP/DFF, but still follows the layout of a RenderWare binary stream file, with three custom sections.
