===Assets===
Assets are the most important part of HIP archives; they're like the files in ZIP archives. Assets hold all of the raw data for textures, models, sounds, and even objects within a level. Assets also have a name, as well as a unique ID (which is generated from the name using a [[Data Types#AssetID|hash algorithm]]). The ID is used by the game to find/identify assets. Assets also have a type ID that tells the game how to interpret the asset's raw data. The asset's data is stored at a specified offset in the [[#DPAK|DPAK]] block. HIP archives do not use any compression for asset data.
Each asset entry is represented by an [[#AHDR|AHDR]] block in HIP archives.
====Types====
A list of all known asset types can be found here: [[Asset#List of asset types|List of asset types]]
===Layers===
Layers are used by HIP archives to group assets of specific types together. Layers have a type ID that specifies what "category" of asset types they contain. For example, <code>TEXTURE</code> layers contain all of the [[RWTX]] assets in a HIP archive
Assets in the same layer have their raw data stored next to each other in the [[#DPAK|DPAK]] block. This is mainly done to optimize the memory layout of assets in-game, as well as enforce the order in which assets are loaded (e.g. <code>TEXTURE</code> layers must be stored before <code>MODEL</code> in order for textures to be applied to models properly).
Each layer entry is represented by an [[#LHDR|LHDR]] block in HIP archives.
====Types====
The following table lists all known layer types and their corresponding type IDs in each game. An empty cell means the layer type is not present in the game.
