Objective

• Asset processors are currently looked up by their TypePath. This means that processors types are not reusable. Once you create a processor of a particular type, you'll need to create a new type altogether to configure things differently.
  • This prevents a processor type to be used "dynamically". For example, you can't define a processor using a scripting language: you'd need to create a brand new type in Rust to do the processing.
  • For another example, LoadTransformAndSave must be generic, so that each combination of AssetLoader, AssetTransformer, and AssetSaver is a unique type (as opposed to having one non-generic type that is dynamically assembled). This prevents us from having an AssetTransformer/AssetSaver registery and then assembling the appropriate processor entirely from the meta file.

Solution

• When registering a processor, you must give a name to your processor.
• Meta files now try to lookup the processor by its name first.
  • To allow for migration, we continue to support type paths for now. This should be deleted after 0.21.

Testing

• Ran the asset processing example and it works!
