Resource Formats Guide
This page provides an overview of the Glacier resource types. Most of the information comes from this talk at 4C on Assets and Entities in Glacier 2.
⚠️ Note: The details presented here are mostly based on resource paths and public talks, and may not be fully accurate or complete.
Understanding the Resource System
Source Resources vs. Intermediate Formats vs. Derived Resources
-
Source Resources: Created by developers and artists using Digital Content Creation (DCC) tools or custom editors. These are platform-independent and are usually stored in human-readable formats.
-
Intermediate Formats: Generated automatically by the build system from source resources. Intermediate formats serve as a bridge between source and derived resources. They encapsulate processed data that is not yet fully optimized for runtime but is structured to support efficient conversion into derived formats.
-
Derived Resources: Automatically generated by the build system from source or intermediate formats. These resources are optimized for runtime performance and are platform-specific, usually stored in binary formats. Derived resources are the final assets used by the game.
