🎨 RetroForge StyleCaster
A powerful ComfyUI prompt builder designed for Flux2Klein workflows that transforms any input image into stunning stylized 3D renders with modular control.
⚠️ Important Notice
RetroForge StyleCaster is designed for creative stylization and artistic experimentation.
Because of how Flux2Klein models work, extreme 3D stylization and perfect facial likeness cannot be fully achieved at the same time.
The stronger the collectible figurine effect becomes, the more the model naturally reinterprets facial proportions.
Recommended settings for maximum identity preservation
Stylization: LOW
Identity Strength: STRICT
Animated Stylization: OFF
Final results always depend on:
Source image quality
Model version
Prompt
Overall stylization strength
Designed by artists, for artists.
No coding required.
Choose a preset for instant results or unlock complete creative control with 13 modular parameters.

➕ Extra
base_prompt

Use this field to customize the core request or improve facial preservation by adding phrases like:
sharp facial features
detailed face
accurate face likeness
extra_positive
Append additional prompts, LoRA triggers or custom instructions without modifying the main prompt.
💡 Pro Tips
👻 Horror
Use:
Animated Stylization → OFF
Expression Protection → STRICT
Pixar-style eyes immediately reduce the horror atmosphere.
🎞️ Vintage Posters
Recommended combination:
Grunge Overlay → MEDIUM
Lighting Mood → NOIR
Background Mode → STUDIO
Increase to HEAVY or EXTREME for distressed poster effects.
🙂 Maximum Identity
Use:
Identity Strength → STRICT
Color Fidelity → HIGH
Expression Protection → STRICT
Then add:
sharp facial features
accurate likeness
to base_prompt.
This improves facial preservation, although it may slightly reduce stylization strength.
🌆 Cyberpunk
For vibrant neon artwork combine:
Lighting Mood → NEON
Material Quality → METALLIC
Color Fidelity → LOW
This allows the model to freely recolor the image into a cyberpunk palette.
🔤 Typography
If the source image already contains text:
Use PRESERVE or AUTO.
Choose NONE if you want to remove all text.
⚖️ Identity vs Style
Flux2Klein naturally prioritizes stylization at higher settings.
If facial accuracy is more important than artistic transformation, start with:
Stylization → LOW
Identity Strength → STRICT
Then reinforce the prompt using face-specific keywords inside base_prompt.
🧠 Advanced Techniques
🎯 Multi-Reference Trick for Better Identity Preservation
The included workflow uses two reference images instead of one to achieve stronger identity preservation while maintaining stylized 3D results.
🖼️ Reference Image #1
Your original image provides:
Color
Texture
Lighting
Overall appearance
This tells the model what to generate.
✏️ Reference Image #2
The same image is processed using AIO_Preprocessor before being supplied as a second reference.
This version provides:
Facial structure
Body proportions
Pose
Overall outlines
Unlike ControlNet, this image is not used as a control signal.
Instead, it is passed directly into Flux2Klein's native multi-reference conditioning, allowing the model to blend information from both references simultaneously.
💡 Why It Works
Flux2Klein attempts to satisfy both conditioning sources at the same time.
The first image describes:
"What should be generated?"
The second image describes:
"How should it be structured?"
The result is often:
Better facial proportions
Stronger pose consistency
Improved identity preservation
Cleaner 3D stylization
...all without relying on ControlNet.
🎨 Choosing the Right Preprocessor
✏️ Lineart
Best for
Portraits
Faces
Clear outlines
Why use it
Provides the strongest facial structure preservation and is the recommended starting point for most portraits.
📐 Canny
Best for
Hard edges
Architecture
Mechanical objects
Why use it
Excellent for preserving sharp contours and geometric detail.
🌄 Depth
Best for
Complex scenes
Interior spaces
Environmental renders
Why use it
Adds spatial awareness and improves perspective consistency.
🧱 Normal Map
Best for
Surface relief
Material detail
Mechanical assets
Why use it
Helps preserve surface topology and fine material information.
⭐ Recommended Starting Points
For most projects:
Portraits → Lineart
Objects & Architecture → Canny
Complex Scenes → Depth
Different source images respond differently, so don't hesitate to experiment.
⚙️ Recommended Settings
For the best balance between identity preservation and stylization:
Preset: CLEAN_3D (or any preset you prefer)
Stylization: LOW
Identity Strength: STRICT
Expression Protection: STRICT
Animated Stylization: OFF
⚠️ Technical Note
This workflow takes advantage of an undocumented behavior in Flux2Klein's native multi-reference blending.
Because this behavior is not officially documented:
Results may vary between model versions.
Different preprocessors may produce different outcomes.
Future updates could change how this behaves.
Treat it as an advanced optimization technique rather than a guaranteed feature.
🔧 Recommended Companion Nodes
RetroForge StyleCaster works best as part of a larger workflow.
Here are two companion nodes that pair exceptionally well with it.
📐 ZImageResolutionScaler
🔗 https://civarchive.com/models/2344436/z-image-resolution-picker
Automatically resizes images to resolutions that work best with Flux2Klein models.
Why use it?
Flux models are surprisingly sensitive to input resolution.
Feeding very large images (such as 4K photos) often introduces facial artifacts or inconsistent stylization.
ZImageResolutionScaler automatically finds a more suitable working resolution before generation begins.
🔤 Simple Text Overlay Node
🔗 https://civarchive.com/models/2711044/simple-text-overlay-node
Adds crisp text overlays after rendering.
Perfect for:
Movie titles
Logos
Captions
Credits
Poster typography
Why use it?
StyleCaster can preserve existing text reasonably well, but generating new readable text is still unreliable.
Adding typography as a post-process produces much cleaner and more professional results.
🔧 Installation
Installation takes only a few seconds.
Extract the RetroForge-StyleCaster folder.
Copy it into:
ComfyUI/custom_nodes/
Restart ComfyUI.
Find the node under:
prompt → builders
You're ready to create.
⚠️ Limitations & Notes
3D Stylization vs Facial Accuracy
This is a limitation of Flux2Klein models—not a bug in StyleCaster.
As stylization increases, the model naturally begins to reinterpret facial anatomy.
Higher stylization creates stronger collectible and animated aesthetics, while lower stylization preserves facial identity more faithfully.
Finding the right balance between style and likeness is part of the creative process.
