ComfyUI-SceneWeaver

Build scenes you didn't think to ask for.

SceneWeaver turns natural-language T2I prompting into a scene-building system. Instead of throwing a pile of tags at your model and hoping for the best, it assembles complete, coherent scenes from characters, environments, objects, styles, and relationships. Currently it has rich Sci-Fi, Fantasy, and Horror offerings.

And the fun part? You can mix them however you want.

Make a two-headed troll fight a mech. Plop an alien spacefarer into a haunted Victorian mansion. Throw your favorite character into a completely different genre and let SceneWeaver figure out how everything fits together. Infinite variety and combinations to explore!

What makes it interesting?

• Cross-Genre Scene Mixing - Entities and environments aren't locked to the same genre. Build the scene you actually want, even when the pieces were never designed to go together.

• Actual Scene Logic - SceneWeaver isn't just picking random words. Its rules understand relationships between things, so the resulting scenes make sense instead of becoming accidental AI surrealism.

• Natural-Language Prompts - It produces rich, grammatical English sentences rather than comma-separated tag soup. This makes it particularly useful with modern natural-language models.

• Scene-Aware Detail Budgets - Add more entities and SceneWeaver intelligently reduces unnecessary environmental detail, helping keep the important stuff from getting lost in prompt bloat.

• Structured + Human-Readable Output - Get both the finished prompt and structured JSON describing exactly what was generated.

• Take Control or Let Fate Decide- Set Fantasy or Sci-Fi scenes to peaceful vs conflict, or Horror scenes to gory vs. no gore (no gore is default) and then choose situation, type of entity, and many other variables to get the sort of scene you want. Or do my favorite thing and set all to random... go hog wild!

Works With Your Model

The included workflow uses Krea2, but SceneWeaver isn't a Krea2 tool.

It is designed for any T2I model that understands natural language so is model-agnostic!

No Style Built-In - Purposefully

No styles have been incorporated into the resulting prompts to allow users to choose their preferred output. Feel free to concatenate your preferred style, experiment with loras, or pipe through Stylebook (Reference CivitAI post or Github)! An example workflow using Stylebook is also included with this post.

Want to make it weirder?

The vocabulary and scene systems are meant to grow.

Tell me what you'd like SceneWeaver to be able to generate. New genres, characters, environments, objects, relationships, or completely ridiculous combinations are all fair game. If there's a kind of scene you want to build, let me know.
