-====== Creating tileable textures from reference images ======
-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.
-==== Gimp ====
-=== Method one: Map Filter ===
-  * 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.
- {{ :ig.guidelines:gimp_1.png?nolink |}}
-  * Click 'Filters' -> 'Map' -> 'Tile Seamless'. Your texture is now tileable.
-  * Adjust the resolution as needed.
-{{ :ig.guidelines:gimp_2.png?nolink |}}
-=== Method two: Clone tool ===
-  * Click on  'Layer' -> 'Transform' -> 'Offset'
-  * Click 'By width/2, height/2' and confirm with 'OK'
-{{ :ig.guidelines:gimp_3.png?nolink |}}
-  * 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.
-=== Checking the tiling in Gimp ===
-  * 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 2667x2667 texture tiled in a Canvas size of 8001x5334
-{{ :ig.guidelines:gimp_4.png?nolink |}}
-==== IMGonline ====
-  * 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.
