The Material Update

The primary focus of this update is to improve the world texture/material pipeline. This not only includes animated textures and better-looking materials by default, but a complete overhaul to the internal asset management system to make it more versatile overall.

Warning: This release updated the Vcap and Replay specifications. Older versions of the Blender addon may not be able to import files from newer versions of the mod!

Changes

• Re-organized Vcap export context

  • Instead of being hard-coded to save world materials and textures, export context now contains a "material provider" system which can save an arbitrary amount of materials and textures.

  • The same goes for models. Model entries have been replaced by model providers (which BlockModelEntry is a subclass of) that supply their own mesh writing function.

• Updated ReplayTexture

  • Replay textures may now specify "dependency" textures, which are written to disk alongside the primary texture.

    • Used for animated textures.

  • Added prepare() method to execute pre-serialization functions (such as GPU texture extraction) asynchronously.

  • Wrote TextureSerializer utility class that unifies the code of writing textures to Vcap and Replay zip files.

  • NativeImage extractor now uses a byte array rather than saving and reading from disk.

• Added support for emission in the Unified Material System.

  • emission and emission_strength fields.
  • Emissive blocks are properly exported.

• Exporter now supports animated textures

  • Unified Material System now includes a specification for animated textures.

  • Blocks with animated textures are given their own materials rather than using the atlas.

    • Detection and extraction of spritesheet.

  • Implemented spritesheet decoding in Blender

• Fixed an issue in the Blender addon where materials in subdirectories of a Vcap would not be imported properly.
