+====== How to Make a Texture Tileable in Substance Sampler Without Using AI ======
+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.
+==== Step 1: ====
+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. Additionally, you can adjust the Patch Size.

+==== Step 2: ====
+It is important to change the output to Basecolor.
+==== Step 3: ====
+Various filters can now be applied depending on the texture. The following filters are generally available:
+== Crop: ==
+Use this filter if you need to adjust the texture's framing. This should be the first operation performed before other filters.
+== Equalize: ==
+This filter balances the brightness and contrast of the texture to create a more uniform look.
+I recommend setting the Radius value to 9, as this works well for most textures.
+Be cautious when using the Equalize filter, as it can remove structural details from the texture. Avoid enabling Keep Local Differences; while it can restore some structure, it may also introduce visible tiling artifacts.
+== Make it Tile or Tiling: ==
+These filters help create seamless textures.
+Make it Tile provides more advanced options for controlling the tiling process, while Tiling is more straightforward. Choose the one that best suits your specific texture and workflow requirements.
+== Warp or Warp Transform:==
+Warp Transform provides more control for adjusting seams. It is important to note that Warp Transform should be applied below the Tiling filters and above the Equalize filter.
+The Warp filter can be used as a final step to introduce additional variation and enhance the tiling effect.

+====== Nodes in Substance Designer ======
+===== Transform 2D Node ======
+The Transform 2D node in Substance Designer allows you to move, scale, and rotate textures on a 2D plane. It is particularly useful for aligning, enlarging, or rotating patterns.
+This happens because Substance Designer has **Tiling** enabled by default to seamlessly fill the 2D space. When you scale a texture with the Transform 2D node and move it outside the UV space (0–1), the texture automatically tiles, as Substance Designer is optimized for procedural workflows.
+The reason the texture may **not remain seamless** is due to edge transitions: if the texture wasn’t originally seamless, tiling will reveal visible seams at the borders. Even if the texture is seamless, scaling or rotations can introduce interpolation artifacts, causing small differences at the edges.
+{{ :ig.guidelines:transfom_2d_node_1.png?nolink&400 |}}
+How to avoid this:
+  - Use the **Make it Tile** node to ensure your texture is seamless.
+  - Disable tiling by setting the area outside the texture to transparent or a solid color in the Transform 2D node.
+  - Avoid extreme scaling, as this can amplify artifacts.
+  - Only scale within the bounds of the texture area to prevent tiling issues.
