FThumbnailBaseAssetProcessor

Reusable base class for asset processors that operate via on-disk thumbnails.

API > API/Plugins > API/Plugins/SemanticSearch

Reusable base class for asset processors that operate via on-disk thumbnails.

Derived classes must:

  • Implement GetProcessSubBucketName() tell the system where to store the derived
  • Implement GetMetadata(InAsset) to supply structured per-asset metadata.

Derived classes may optionally override GetRevision() to bump cached data if they their implementation details.
