Master Reference Assets
Before you start generating variants, refining outputs, or scaling creative directions in Luma, establish your Master Reference Assets.
Your Master Reference Assets are the immovable elements of your project — the non-negotiables that define identity and consistency. Think of them as the Agent's single source of truth.
These can include:
- A logo and its placement rules
- A brand color system
- A character’s face, proportions, and wardrobe
- A product’s exact physical design
- A specific lighting style
- A defined tone of voice
- A tagline that must remain unchanged
Luma is designed for exploration and scale. You can generate dozens of variations from a single prompt. You can branch into new formats. You can transform images into video, add voiceover, localize, restyle, extend, and reframe.
but…
Iteration without anchoring tends to drift.
When you tell the Agent to fix this version or generate another option, it naturally optimizes from the most recent output. If you don’t explicitly remind it to reference the original Master Reference Assets, small deviations can compound:
- A character’s facial structure shifts slightly.
- A logo subtly changes proportions.
- A brand color drifts warmer or cooler.
- A product’s shape becomes approximate.
- A tagline mutates over iterations.
At first, the changes are subtle. Over time, they become inconsistencies.
Master Reference Assets prevent creative entropy.
They ensure that while exploration expands outward, identity remains stable.
In a system built for scale, anchoring is discipline.
Ask for edits with context
Luma allows you to iterate quickly and generate many variations from a single input.
But the more you scale, the more intentional you must be in your instructions about what stays constant.
When refining a version, don’t just reference the last output – re-anchor the Agent to your original Master Reference Assets.
Instead of:
Fix the lighting on this.
Say:
Fix the lighting while preserving the exact character proportions, logo placement, and color palette from the Master Reference Assets.
That small shift in instruction protects the integrity of your project across every transformation — image to video, video to localization, edit to extension.
Consistency doesn’t happen automatically. It’s maintained deliberately.
Key takeaway
Before you scale, define your Master Reference Assets.
As you iterate, always re-anchor to them.
In Luma, creativity can expand infinitely — but identity should remain intentional and grounded in a clear single source of truth.
Turn Your Files Into Creative Assets
One of the most powerful things about working with Luma's multimodal Agent is this:
You don’t have to start from scratch.
You can upload your own materials—PDFs, scripts, images, videos, briefs, decks, references, audio tracks—and ask the Agent to:
- understand them
- summarize them
- extract what matters
- turn them into creative-ready building blocks
- generate outputs based on them
If you give the agent good inputs, you can move faster, stay consistent, and avoid “random AI results.”
Tell the agent what you uploaded and what you want
A common mistake is uploading a file and saying:
Make [something] with this.
Instead, select the file you’ve uploaded and say this to the agent:
Prompt template
I’ve uploaded this file.
Your job is to:
1) understand what it contains
2) summarize it clearly
3) ask me what output I want to create from it
Before generating anything, tell me what you think this file is and what it can be used for.
This makes the agent “look before it acts.”
What you can ask the agent to do with uploaded assets
Summarize it
Best for: long PDFs, raw notes, research, briefs
Prompt template
Summarize this file in [10] bullet points.
Then give me:
- the [3] most important takeaways
- the [3] things that are unclear or missing
- the [3] most useful next steps
Extract the important parts
Best for: scripts, text docs, briefs, pitch decks
Prompt template
Extract the most important parts of this file.
Organize them into:
- key facts
- key goals
- key constraints
- key tone/style notes
- key deliverables
Turn it into a creative brief
Best for: messy notes, email threads, unstructured PDFs
Prompt template
Turn this file into a clean creative brief.
Format it as:
- Project Summary
- Target Audience
- Tone and Style
- Key Messages
- Must-Haves
- Avoid / Don’t Do
- Deliverables
- Open Questions
This is one of the most valuable tasks because it turns chaos into clarity.
Turn it into instructions you can actually use
Best for: any file you want to create outputs from
Prompt template
Based on this file, write [10] high-quality prompts I can use.
Each prompt should:
- be specific
- include style guidance
- include what should stay consistent
- include what can vary
Make them copy/paste templates with placeholders.
Create a plan before generating
Best for: larger projects like trailers, campaigns, story worlds
Prompt template
Based on this file, propose a step-by-step plan to create final outputs.
Please include:
- what assets we should generate first
- what we should lock early (style, characters, tone)
- where iteration will be needed
- what can be done in parallel
Check for problems or contradictions
Best for: brand docs, scripts, story bibles, spec sheets
Prompt template
Review this file for:
- contradictions
- unclear parts
- missing information
- places where a human would need to make a decision
Then ask me the questions you need.
This is extremely useful for reducing mistakes later.
Turn it into a storyboard / shot list for video
Best for: scripts, voiceovers, trailer outlines
Prompt template
Using this file, create a shot list.
For each shot:
- what we see
- what we feel
- camera style
- key visual details
- what must stay consistent
Turn it into a character reference system
Best for: story docs, character descriptions, lore
Prompt template
Extract the character information from this file.
For each character:
- appearance
- personality
- key identity markers
- “must not change” rules
Then write a short reusable character reference block I can paste into future prompts.
Turn it into a “style guide” for consistency
Best for: reference image sets, art direction docs, moodboards
Prompt template
Turn this file into a visual style guide.
Include:
- color palette
- lighting rules
- texture/material rules
- composition rules
- camera language (if relevant)
- what to avoid
Write it in a format that can be reused in prompts.
Use it as “truth” so the agent doesn’t make things up
Best for: anything where accuracy matters
Prompt template
Use this file as the source of truth.
If something is not stated in the file:
- do not invent it
- instead, ask me a question
This is a big one. It prevents hallucinated details.
What types of files can you upload?
You can upload almost anything that helps the agent understand your intent, such as:
Text-based Files
- PDFs
- scripts
- voiceover documents
- briefs
- pitch decks
- brand guidelines
- story bibles
- meeting notes
Visual Files
- reference images
- moodboards
- character sheets
- product photos
- screenshots
Video Files
- clips you want to remix (V2V)
- motion references
- prior versions of your own video work
Audio Files
- voice samples
- rough reads
- music references (depending on tool support)
The most useful workflow
Upload → Analyze → Convert → Create
If you want a simple repeatable flow, use this every time:
Prompt template
Step 1: Summarize what’s in this file.
Step 2: Extract the important creative constraints.
Step 3: Turn it into reusable building blocks:
- brief
- character references
- style guide
- shot list (if video)
Step 4: Propose [3] output directions I could generate.
This turns the agent into a creative producer.
A helpful reminder
Uploading assets doesn’t just “give the agent content.”
It gives the agent:
- constraints
- style
- continuity
- context
Which means:
you get less randomness and more control.
If you provide strong inputs and ask for the right kind of analysis, the agent can do a huge amount of work for you—before you generate a single frame.
It can:
- organize your materials
- convert them into usable creative building blocks
- and help you produce consistent, professional outputs faster.
Using Master References
Create Your Master Reference Assets Pack
At the start of a project, define and group:
- Final logo file
- Approved brand colors
- Character reference images
- Product reference renders
- Tone-of-voice document
- Key messaging lines
Place them clearly on your board in a dedicated frame labeled:
Master Reference Assets or something similar that you will tell the Agent to reference as its source of truth
Keep them visually separated from exploration zones, label each asset clearly, so if you have 3 versions of your logo that you've uploaded to your board, label each version clearly e.g. "logo01, "logo02", "logo03" that way you can give the Agent a clear path to understanding which asset you may be talking about in your written instructions/prompt.
Establish What Is Immovable
Explicitly define:
- What can change?
- What cannot change?
Example:
Can change:
- Lighting
- Background
- Camera angle
Cannot change:
- Character face
- Logo proportions
- Brand typography
- Product design
Clarity here prevents drift later.
Anchor Every Major Iteration
When generating new versions, say things like:
Use the Master Reference character.Preserve logo placement from Master References.Maintain exact product dimensions from Master Reference.Keep brand color system consistent with Master Reference Assets.
This keeps each branch tethered to the source.
Avoid Iteration Chains Without Re-Anchoring
Common mistake:
Version 1 → tweak
Version 2 → tweak
Version 3 → tweak
Version 4 → tweak
By Version 6, the character no longer matches the original.
Instead:
Every few iterations, restate:
Reconfirm against Master Reference Assets.
This resets drift.
Use Master References Across Modalities
When transforming formats:
- Image → Video
- Video → Stylized version
- English → Localized voiceover
- Static → Animated
Always re-anchor.
Example Prompt:
Animate this scene while preserving the character proportions and product design from the Master Reference Assets.
Multimodal transformation increases drift risk — so anchoring becomes even more important.
Protect Brand Integrity at Scale
When generating large batches:
- 20 hooks
- 10 video variants
- 5 tonal versions
Keep brand identity consistent by referencing:
- Approved messaging
- Tone guidelines
- Visual system
Scale should multiply reach — not multiply inconsistency.
Use Evaluation as a Final Check
Before delivering:
- Compare outputs side-by-side with Master References.
- Ask the Agent to evaluate alignment.
- Confirm that no key elements drifted.
This is especially important for:
- Enterprise brand work
- Character-driven campaigns
- Product visualizations
- Franchise-style creative systems
The Core Principle
Exploration expands.
Identity anchors.
Luma enables infinite creative branching — but the most professional work always maintains a stable center.
Your Master Reference Assets are that center.
