How to Create Stone Textures

📌 Textures used: Poly Stone Texture Collection

This guide will walk you through the process of using Poly’s AI to generate stone textures. We’ll focus on creating textures for various types of stone — such as granite, limestone, and sandstone — and we’ll share examples of effective prompts that will help you achieve the best results.

Step 1: Creating Patches

To begin, navigate to the Make Patches section in Poly. Create a detailed text prompt that describes the stone texture you want to generate. Remember to include information about the texture’s category, styles, types, descriptors, environment, and detail. Here are some examples of good prompts for stone textures:

• "Polished granite stone, dark gray with white speckles, smooth surface, suitable for kitchen countertops, high-resolution texture"
• "Weathered limestone wall, light beige color, uneven surface with cracks and crevices, aged appearance, high-definition texture"
• "Red sandstone rock, layered and eroded surface, desert environment, warm color tones, detailed and realistic texture"

Enter your prompt and press enter. In a few seconds, you’ll see four high-quality patches to choose from. Iterate as many times as you want until you find a patch that you like; then confirm your selection.

Step 2: Making the Texture Seamless and Scaling

Now that you have a low-resolution texture patch, navigate to the Make Seamless toolbar to create a seamless, tileable texture. For stone textures, the AI should be able to expand the surface area of your patch without causing unwanted artifacts or seams. The default 80% scale should work well for most stone textures, but feel free to experiment with other values if necessary.

Step 3: Upscaling the Texture

If you need to upscale your texture, navigate to Upscale Texture and press enter. In a couple of seconds, the upscaling process will complete, and your texture will be in 1K, 2K, 4K, or 8K HD resolution.

Step 4: Generating PBR Maps

The final step is to add PBR maps to your stone texture. Navigate to Generate PBR Maps to get started. Select the most suitable material type for your stone texture. For natural materials, you may want to experiment with options like Dramatic, Organic, Polished, or Matte. Keep in mind that:

• Dramatic works best for textures with noticeable amounts of displacement, such as layered or eroded stone surfaces.
• Organic is a good middle ground between strong and weak displacements, suitable for materials like weathered limestone or aged stone walls.
• Polished is best for surfaces with a natural sheen and little to no displacement, such as polished granite or marble.
• Matte is suitable for flat surfaces with few irregularities; it produces a smooth and gently lit appearance.

Once you’ve selected the appropriate material type, the PBR maps will be added to your view. You can preview your seamless stone texture on a sphere, or adjust the Render and View options for a better preview before downloading your texture in either 8-bit JPG or 32-bit EXR format.

By following these steps and creating detailed prompts, you can use Poly’s AI to generate high-quality, seamless stone textures for various applications, from architectural design to video game environments.
