Fantasy landscape creation with AI has traditionally suffered from inconsistency. Each generated image stands alone, making it nearly impossible to build coherent worlds across multiple generations. Midjourney V7’s Omni Reference feature changes this by allowing style consistency across images, enabling true world-building with consistent aesthetics.
This guide teaches you how to leverage Omni Reference for fantasy landscape work, providing 12 prompts that demonstrate different applications of this powerful feature.
Understanding Omni Reference
Omni Reference (—oref) accepts multiple image URLs that Midjourney uses to maintain aesthetic and thematic consistency across generations. Unlike style reference which focuses on visual aesthetic, Omni Reference helps maintain world-building coherence: geography, atmosphere, architecture, and magical systems can remain consistent across images.
The practical benefit is creating portfolio pieces or narrative art sequences that feel like they belong to the same world rather than unrelated generations.
Prompt 1: Ancient Forest Realm
Prompt: “Fantasy landscape of ancient primordial forest, trees with bark resembling carved stone, bioluminescent moss providing ambient light, Undergrowth of ferns and flowering plants, mist between trunks, mythical atmosphere, —ar 16:9 —v 7 —oref [forest reference image URL]”
This prompt establishes an ancient forest with consistent organic architecture. The reference image should establish the forest’s key visual elements.
Prompt 2: Floating Sky Islands
Prompt: “Fantasy landscape of floating islands suspended in sky, waterfalls cascading into clouds below, vegetation on island undersides, ancient ruins on plateau surfaces, dramatic cloudscape, sense of impossible scale, —ar 16:9 —v 7 —oref [island reference image URL]”
Sky islands require consistent gravity-defying elements. The reference establishes how islands connect to their surroundings.
Prompt 3: Crystal Cavern System
Prompt: “Fantasy landscape of vast underground crystal cavern, formations emitting own light in varied colors, underground lake reflecting formations, scale impossible to judge, otherworldly mineral atmosphere, —ar 16:9 —v 7 —oref [cavern reference image URL]”
Crystal caverns benefit from consistent lighting interpretation. The reference establishes the crystal aesthetic and light behavior.
Prompt 4: Desert Sorcerer City
Prompt: “Fantasy landscape of desert city built into canyon walls, sand-colored structures blending with rock, narrow streets and passages, market activity visible, heat shimmer effect, terracotta and gold color palette, —ar 16:9 —v 7 —oref [city reference image URL]”
Desert cities require consistent architectural language and atmospheric treatment. The reference establishes the building style and environmental conditions.
Prompt 5: Frozen Northern Reaches
Prompt: “Fantasy landscape of frozen tundra at twilight, aurora borealis overhead, ice formations along horizon, wind-carved snow structures, minimal color palette of blue and white, sense of isolation, —ar 16:9 —v 7 —oref [arctic reference image URL]”
The northern reaches need consistent cold atmosphere and aurora behavior. The reference establishes the light and color interactions.
Prompt 6: Volcanic Forge Lands
Prompt: “Fantasy landscape of volcanic region, active lava flows near ancient fortress, heat distortion visible, orange and black color palette, smoke and ember particles, industrial architecture integrated with geology, —ar 16:9 —v 7 —oref [volcanic reference image URL]”
Volcanic landscapes require consistent fire and heat effects. The reference establishes how smoke, light, and color interact.
Prompt 7: Submerged Atlantis Ruins
Prompt: “Fantasy landscape of underwater ruined city, shafts of light from surface penetrating water, coral growing on structures, fish swimming through archways, turquoise water filtering light, sense of ancient grandeur, —ar 16:9 —v 7 —oref [underwater reference image URL]”
Underwater ruins need consistent water light behavior. The reference establishes how light rays and color filtering work in this world.
Prompt 8: Mushroom Forest Floor
Prompt: “Fantasy landscape of forest floor dominated by massive mushrooms, varying heights creating depth, bioluminescent caps providing illumination, tiny creatures visible, fairy-tale atmosphere, saturated color palette, —ar 16:9 —v 7 —oref [mushroom reference image URL]”
Mushroom forests require consistent fungal architecture. The reference establishes scale relationships and light behavior.
Prompt 9: Storm-Racked Cliffs
Prompt: “Fantasy landscape of dramatic coastal cliffs during storm, waves crashing below, lightning illuminating scene intermittently, wind affecting vegetation, dark dramatic sky, sense of raw power, —ar 16:9 —v 7 —oref [coastal reference image URL]”
Stormy coastlines need consistent weather behavior. The reference establishes how lightning and waves appear in this world.
Prompt 10: Autumn Wizard’s Domain
Prompt: “Fantasy landscape of autumnal magical realm, fallen leaves creating carpet, ancient stone tower in distance, warm light from tower windows, gentle magic suggested by floating leaves, golden hour lighting, nostalgic mood, —ar 16:9 —v 7 —oref [autumn reference image URL]”
Wizard domains require consistent magical atmosphere. The reference establishes how magic manifests visually.
Prompt 11: Jungle Temple Complex
Prompt: “Fantasy landscape of overgrown temple emerging from jungle, vines covering structures, trees growing through ruins, moss and ferns on stone surfaces, hidden entrance suggested, sense of forgotten knowledge, —ar 16:9 —v 7 —oref [ruins reference image URL]”
Jungle temples need consistent vegetation-stone relationships. The reference establishes how quickly nature reclaims structures.
Prompt 12: Starlit Plateau
Prompt: “Fantasy landscape of elevated plateau at night, thousands of stars visible due to altitude, low vegetation adapted to altitude, distant mountains visible, ethereal mist, contemplation and wonder mood, —ar 16:9 —v 7 —oref [night landscape reference image URL]”
High altitude night landscapes require consistent star field and atmospheric behavior. The reference establishes celestial and terrestrial relationships.
Building Worlds with Omni Reference
Effective world-building requires establishing reference images for each major environment type before generating variations. Spend time perfecting reference images because they control consistency across all subsequent generations.
Consider creating references for key elements: architecture, vegetation, lighting conditions, and atmospheric effects. These modular references can be combined for complex scenes.
Key Takeaways
- Omni Reference enables world-building consistency across generations
- Establish environment-type references before generating variations
- Reference images control aesthetic coherence, not just style
- Modular references for architecture, lighting, and atmosphere can combine
- Invest time in reference images for better final outputs
FAQ
How many references should I use with —oref? Typically one strong reference works best. Multiple references blend their influences, which can dilute the consistency you’re trying to achieve.
Where do I find good world-building references? Concept art from fantasy games and films, landscape photography with appropriate mood, and historical architecture all work well.
Can I use AI-generated images as references? Yes, using your own consistent AI generations as references creates a closed feedback loop of style consistency.
How does —oref differ from —sref? Style reference (—sref) controls visual aesthetic like color and lighting. Omni Reference (—oref) helps maintain world-building coherence across multiple scenes.
What’s the difference between 16:9 and other aspect ratios for fantasy landscapes? 16:9 works well for desktop wallpapers and cinematic presentations. Square (1:1) formats better suit social media and portfolio presentation.
