DoubaoSeedream45 is a UE5 plugin for Volcano Engine Doubao Seedream, offering API key verification, single generation with cancel support, batch queue processing (per-item progress + completion callbacks), prompt rewriting (style mode and sampling controls), and a stream-style node wrapper (currently implemented via fallback single-generation with text/image chunk broadcasts).

Requests support model/resolution/aspect-preference settings, watermark toggle, output directory, and multi-reference input (local paths or URLs, batch-separated by semicolon/comma/newline).

It automatically saves outputs and maintains history records with thumbnails.

The Blueprint library includes history read/write (`SaveHistoryRecords` included), clear/remove/delete operations, prompt-library CRUD/search, model/aspect helpers, image splitting, and thumbnail-path selection.

The editor panel provides CN/EN switching, unified loading/log UI, a reference-image grid (multi-image display, selected preview, per-image enable/disable for generation, enable-all/disable-all, remove, import from history, capture from viewport), prompt/history management, queue build/run workflow, ellipsis + tooltip text handling, interactive split-grid and tile preview, quick open for output folders, and level-viewport overlay preview.
