Using Prompt Expressions

You can add or decrease the 'weight' of your prompts or groups of words in a prompt by using Scenario's Prompt Expressions

The weight of a prompt refers to how strongly the model’s neural network emphasizes specific elements when generating an image. By adjusting the prompt, you can control how prominently different aspects appear in the final output.

For example, consider the following prompt used with Scenario’s "3D Style Chibi Characters" model:

Prompt: a tomb-diving woman with an athletic build and a determined expression, colorful clothing
Seed: 2852957936000098291

Adding a New Style

If you want to introduce a "Voxels" style to this image, simply add the word "Voxels" to the prompt:

Prompt: a tomb-diving woman with an athletic build and a determined expression, voxels, colorful clothing

Increasing Weight with Operators

You can fine-tune the influence of specific words in your prompt using operators.

Use the '+' symbol to make a word more prominent in the image. Multiple '+' signs will amplify the effect.
    • Example: a tomb-diving woman with an athletic build and a determined expression, voxels++, colorful clothing

Grouping Words for Weighted Emphasis

To apply weight to a group of words, use parentheses:

  • Example: a tomb-diving woman with an athletic build and a determined expression, (voxels style)++, colorful clothing

Nesting Operators for Precision

For even more granular control, you can nest operators within parentheses. This method allows you to combine weights for maximum effect:

  • Example: a tomb-diving woman with an athletic build and a determined expression, (voxels++ style)++, colorful clothing

3D Style Chibi Characters_McTG3fRmTpS9jMmQZxR6rw_a tomb diving woman with an athletic build and a determined expression (voxels++ style)++, colorful clothing_inference-txt2img_1712252009

Reducing Weight on Specific Elements

If you want to downplay certain aspects, you can reduce their weight, even when combined with other elements. Use the '-' symbol to reduce the influence of a word. Similarly, multiple '-' signs will decrease the effect.

  • Example: a tomb-diving woman with an athletic build and a determined expression, (voxels++ style)++, (colorful)---- clothing

Conclusion

As demonstrated, using operators in your prompts allows for precise control over how different elements influence the generated image. By adjusting the weight of specific words or groups of words, you can fine-tune your prompts to achieve the desired visual results.
