# Sketch to Render / Apply Fabric
## 1. Fabric Upload Guide
### 1-1. Use fabric photos that allow you to check the texture
* Texture, drape, and light response are all naturally represented
* E-commerce **It is recommended to crop only the fabric portion from the product image and use that**
### 1-2. When photographing swatches, adjust saturation
* When shooting with a mobile phone, the colors often become **distorted into gray/yellow tones**
* Since AI reflects these colors as they are, the result may differ
* π Before uploading, simple **brightness/saturation correction** recommended

## **2.** Pattern Scale Adjustment Guide
AI interprets the pattern size in the uploaded image as-is.
Therefore, if the image is distorted:
* Enlarged floral pattern β generated as an excessively large pattern
* Small repeating pattern β expressed too densely
π Result: an unnatural design that differs from the actual garment
### 2.1 Adjust pattern scale with prompts
Even if the image is not suitable,\
you can adjust the scale with a prompt.
{% hint style="info" %}
Because the swatch is zoomed in, adjust the stripe pattern to a realistic garment scale: thin teal and white vertical stripes (approx. 5 mm each), narrow spacing, and multiple stripe repetitions across the entire garment. Maintain clean, continuous alignment.
{% endhint %}
### 2.2 Photograph from the distance at which it appears on clothing
To keep the pattern scale accurate,\
image selection and shooting method are important.
**When you only have a swatch**
* Too close-up shooting β
* Photograph from the distance it would appear on actual clothing β
π Key point: **Make it look like the βactual worn sizeβ**
