DrwResourceMeta

Contains metadata about the DRS resource, specifically a version number and a hash string.

Overview

  • Purpose: Stores basic metadata, primarily a hash likely used for asset identification or version tracking.
  • Where it appears: Present in all defined model types (AnimatedUnit, StaticObjectCollision, StaticObjectNoCollision, AnimatedObjectNoCollision, AnimatedObjectCollision). See WriteOrder.
  • Engine impact: Likely used by the engine or tools for identifying or verifying the asset version. It doesn't directly affect rendering or gameplay mechanics visible to artists.

Structure

Field Type Description
version int32 Format version number, typically 1.
unknown int32 An unknown integer value. Observed values include 0, 1, 2, 3. Default appears to be 1 for units.
length int32 Length of the following hash string in bytes.
hash string A string containing hash information (e.g., "sr-1234567890-0").

Authoring & In-Game Behavior

  • Blender Workflow: This block is generated automatically by the exporter (save_drs calls DrwResourceMeta().write). Artists do not directly edit this data in Blender.
  • Hash Generation: The exporter currently generates a default hash string (""). The specific logic for generating meaningful hashes (like "sr-crc32-0") might reside elsewhere or in older toolchains. The importer (DrwResourceMeta().read) simply reads the existing hash from the file.
  • unknown field: The purpose of this field is unclear.

Validation Rules

Rule Why
version == 1 Confirms expected format.
length matches actual hash string length Prevents reading incorrect data or buffer overflows.

Cross-References

Nice to know

  • Magic Value: DrwResourceMeta = -183033339 (0xF518F885).
  • Although present in all models, the actual meaning or usage of the hash string by the game engine isn't known. It likely serves as a unique identifier or checksum.
