Proposes SceneDecorator, a training-free framework for scene-oriented story generation that uses VLM-guided global-to-local scene planning and long-term scene-sharing attention to keep scenes consistent across multiple stories.

Problem

Story generation with text-to-image models focuses on character consistency and overlooks scenes; it lacks scene-level narrative coherence in planning and scene consistency across multiple stories.

Approach

A VLM conceptualizes a global scene, which a T2I model renders; the VLM then crops it into local scenes and story sub-prompts. Generation uses mask-guided IP-Adapter-style scene injection, scene-sharing attention across story branches, and extrapolable noise blending to scale to many stories with fixed memory.
