Sometimes tiled textures are not provided or are not yet available. In these cases, it can be necessary to create your own textures from existing reference images.

• Choose a appropriate area of your reference image to use as a base. The section should be clear, with no blurriness and no harsh differences in lighting.
• Cut it out to your preferred format. For most cases, this will be square. In Gimp, this can be done with the 'crop tool' or the shortcut shift + C. The desired size can be further adjusted In the tool options.

• Click 'Filters' → 'Map' → 'Tile Seamless'. Your texture is now tileable.
• Adjust the resolution as needed.

• Click on 'Layer' → 'Transform' → 'Offset'
• Click 'By width/2, height/2' and confirm with 'OK'

• Select the 'Clone' tool (shortcut 'C') and choose a soft brush
• Press Ctrl + LMB to select a source area around the seam that is similar to the one you want to blend it with.
• The selected source area will move proportionally to your mouse, so you will have to alternate between selecting a source and blending the seam.
• Repeat until all seams are blended and you are happy with the result.
• Adjust the resolution as needed.

• Click 'Filters' → 'Map' → 'Tile' and set the size to be a couple of times larger than your texture.
• This will create a new image which you can use to check the seamlessness.
• The example shows a 2667×2667 texture tiled in a Canvas size of 8001×5334

• Again, cut out a part of your reference image in the format you want your texture to be tileable in.
• Head to this website https://www.imgonline.com.ua/eng/make-seamless-texture.php
• Upload your cut out part and adjust the settings to your liking.
• Click 'OK'
• You can now view and download the generated texture.
• The site has a built-in option to tile the texture, where you can check the seamlessness.

When creating tileable textures, it is advisable to minimize the use of AI, as it often alters details and results in a texture that no longer resembles the original. The texture import process should also avoid AI. While AI can generate a roughness map or a normal map from the texture, these are often unnecessary if the base color map is sufficiently strong.

In the following steps, care should be taken to preserve the defining characteristics of the texture, particularly its colors and shapes.

Drag and drop the image into Substance Sampler and click on Use as Bitmap. If you have multiple images of the texture taken from different angles, go to Texture Import and drag all the images into the tool—at least 4 images are recommended.
