How ProsePainter 2's Style Sliders and Style Ingredients Work

Updated

ProsePainter 2 builds a custom AI brush by mixing style ingredients on a slider interface: you combine any number of ingredients, optionally add a text prompt, and save the result as a reusable brush. The same brush can also be derived from reference images instead of sliders. This explainer covers both routes, how to steer results with prompts and AI strength, and where ControlNet guides fit in.

The Two Ways to Build a Brush

ProsePainter 2 presents style creation as two complementary paths, both listed on its landing page.

Path 1: Style ingredients with sliders

The site describes an "intuitive style slider interface" where you "mix and match different style ingredients to craft the perfect brush." The stated capabilities are:

  • Combine any number of style ingredients
  • Add custom prompts for more control
  • Save and share your favorite combinations

The mechanism to understand: each ingredient contributes a direction to the style, and the slider sets how strongly that ingredient pulls on the output. Adding an ingredient introduces a new axis; moving its slider changes the blend. Because the site says "any number of" ingredients, the brush is not limited to a fixed pair — you can stack several and tune each one.

Path 2: Style by image reference

Instead of sliders, you can use images as the style source to "create brushes that capture the essence of a particular medium or aesthetic." The listed capabilities:

  • Mix several images to create hybrid styles
  • Capture a section of your work-in-progress to lock in a style
  • Build a library of favorite styles

The third point is the practical bridge between the two paths: a brush made either way can be stored and reused, so your style library becomes the working set you paint from.

A Concrete Example

Suppose you want a brush that reads as ink wash with a faint pencil underdrawing.

  1. Start with ingredients. Add an ink-wash ingredient and a pencil ingredient. Push the ink slider high and keep the pencil slider low so the pencil reads as texture rather than line.
  2. Add a prompt for control. The site supports custom prompts alongside ingredients; a short prompt describing the medium and mood narrows the result further.
  3. Test on a small area. Paint a few strokes, then adjust. If the pencil dominates, lower its slider rather than removing it.
  4. Save the combination. Once the brush feels right, save it so it joins your style library.

If you already have a reference — say a photo of a watercolor wash you like — switch to the image-reference path, mix it with a second image if you want a hybrid, and save that brush instead.

Steering the Output: Prompts, AI Strength, and Guides

Style is only one input. ProsePainter 2 lists three further controls under "Fine-Grained Control" and "ControlNet Guides":

Control What it does When to reach for it
Text prompts Guide the AI in your generations You want subject or content direction, not just style
AI strength Balances your input against AI creativity Output drifts too far from your strokes, or feels too rigid
ControlNet guides Edge and depth maps steer generations with precision You need composition or structure held in place

The AI strength slider is the one most likely to need revisiting: it is the trade-off between what you painted and what the model adds. Lower it when the AI overpowers your marks; raise it when you want more invention.

Working at Canvas Scale

Two canvas features affect how styles behave in practice:

  • Expand and crop seamlessly as the artwork evolves, expanding in any direction up to 5k.
  • Upscale for added detail.

Style consistency matters more once you expand, since new regions are generated in the context of the existing painting. Locking in a style from a section of your work-in-progress — one of the image-reference capabilities — is a way to keep that consistency as the canvas grows.

Exploration Aids

For breaking out of a rut, the site lists randomize your styles for fresh ideas and a range of mirroring options to jumpstart compositions. Randomizing is a fast way to discover ingredient combinations you would not have set deliberately; mirroring helps when you want symmetry without painting both halves.

Deciding Which Route to Use

  • Use sliders and ingredients when you can describe the style you want but have no single image that captures it, or when you want repeatable, tunable control.
  • Use image reference when you have a visual target — a medium, an aesthetic, or a section of your own painting — and want the brush to capture its essence.
  • Mix both when a reference gets you close and a prompt or slider adjustment finishes the job.

The site's framing — "Paint - don't prompt" — signals the intended workflow: prompts and sliders shape the brush, but the painting itself is done by hand.
