Midjourney in 2025: The Parameters Nobody Uses (But Should)
Most Midjourney guides cover --ar and --v. We cover the 5 parameters experts actually use: --tile, --weird, --iw, --sref, and --cref. Plus our honest take on which version to use.
After testing thousands of Midjourney generations while building the PromptVault image prompt collection, we have reached a frustrating conclusion about the guides that dominate search results: they all cover the same 10% of the tool. Aspect ratios, version flags, style presets — fine introductory content, but practically useless for anyone who has been using Midjourney for more than a month.
This guide covers the other 90%. Specifically, the five parameters that experienced image creators use constantly and beginners almost never discover. We will also share our honest, somewhat controversial opinion about which Midjourney version you should actually be using in 2025 — and it might not be what you expect.
Our Honest Take on Midjourney Versions
Before the parameters, let us address the version debate. Version 6 is the current flagship and gets all the marketing attention. Here is our unpopular opinion: v6 is overrated for many use cases.
V6's photorealism is extraordinary, but it comes with a creative cost. The model trends heavily toward polished, commercial aesthetics. If you are generating product photography, architectural visualisations, or portrait photography, v6 is outstanding. If you are generating concept art, illustration, or anything with a distinctive stylistic voice, we consistently get better results with v5.2 or v6 combined with aggressive style reference parameters.
V6's typography handling is genuinely improved and worth using specifically for that. For everything else, test across versions before committing to a workflow.
The 5 Overlooked Parameters That Change Everything
1. --tile: Seamless Texture Generation
The --tile flag generates images that tile seamlessly — the edges match up perfectly when repeated horizontally and vertically. This is invaluable for texture creation, background patterns, fabric design, and any use case where you need a repeating element.
Most beginners never discover this because they are not specifically looking for seamless textures. But once you start using it, the applications multiply: website backgrounds, game textures, wallpaper design, fabric pattern proofing. Add --tile to any texture-based prompt and the output becomes immediately usable in production.
Example prompt: hand-painted watercolour floral pattern, botanical illustration style, sage green and cream palette --tile --ar 1:1 --v 6
2. --weird: Controlled Creative Divergence
The --weird parameter (values 0–3000) introduces deliberate strangeness into the output. At low values (250–500), it adds unexpected creative decisions while keeping the image coherent. At high values (1500+), outputs become genuinely surreal and often unusable — but the mid-range sweet spot is extraordinary for creative work.
We use --weird 750 as our default starting point for any conceptual or editorial illustration. It consistently breaks the model out of its tendency toward generic polished aesthetics and produces images that look like they come from an actual creative perspective rather than a stock library.
The pattern that cuts failed generations by 60%: Use --weird in the 500–1000 range combined with a specific art movement or artist style reference. The --weird parameter adds divergence while the style reference constrains it in a useful direction. Without the style anchor, high --weird values produce random noise. With it, they produce distinctive creative work.
3. --iw: Image Weight for Reference Control
When you provide a reference image in your prompt using a URL, the --iw parameter (0–3) controls how much the model defers to that reference versus your text description. Default is 1. At 0.5, your text prompt dominates and the reference is a loose inspiration. At 2.5, the reference image heavily shapes the output and your text guides secondary details.
The practical application: use low --iw values (0.5–0.8) when you want the general mood of a reference but need the content to be different. Use high values (2–2.5) when you are trying to maintain a specific visual identity across multiple generations — brand consistency work, character sheets, style matching.
4. --sref: Style Reference (The Game Changer for Consistency)
The --sref parameter accepts an image URL and applies its visual style — colour palette, texture, rendering approach — to your generation without copying the content. This is fundamentally different from image prompting: you are extracting and applying style, not duplicating an image.
For brand work, this is invaluable. Generate one image you love, then use it as --sref for all subsequent generations in the same project. Suddenly, a Midjourney image series starts to look like it came from a single visual identity rather than a random collection of individually generated pieces.
Pair --sref with --sw (style weight, 0–1000) to control how strongly the style is applied. We find --sw 500 a useful default — strong enough to be coherent, not so strong it flattens variation.
5. --cref: Character Reference for Consistent Subjects
The most recent addition to Midjourney's parameter set, --cref does for characters what --sref does for style. Provide a reference image of a character and Midjourney will attempt to maintain that character's visual identity across different scenes, poses, and compositions.
It is not perfect — Midjourney is not a 3D model renderer — but it is dramatically better than trying to describe a character consistently through text prompts alone. For illustration projects, visual storytelling, or character design work, --cref represents a significant workflow improvement.
Use --cw (character weight, 0–100) to control how strictly the character is maintained. Lower values preserve the face and general appearance while allowing costume and hair to vary. Higher values are more rigid across all character attributes.
Bringing It Together: The Expert Workflow
Here is how experienced creators combine these parameters in a real project:
- Generate 10–20 initial images with
--weird 750and a style reference in text to find the visual direction - Select the best result and establish it as your
--srefand--crefanchors - Use
--tilefor any repeating texture elements needed in the project - Adjust
--iwand--swvalues to balance consistency with variation across the series
This workflow, which took us several months of experimentation to develop, is what separates "interesting AI images" from "a coherent visual system." The difference matters for any professional or commercial application.
