How to Fix Seams on 3D Models: A Guide to Adjusting UV Padding

Distance between the UV islands should be:

• 512x512 textures = 4px
• 1024x1024 textures = 8px
• 2048x2048 textures = 16px 

If the padding is smaller than specified in the requirements above, visible seams may appear on the 3D model. If this happens, the padding should be increased. To make this process easier, we offer a script that helps rebake the textures from the old UV to the new one.

How to use:

1. Create a new UV with the correct padding.
2. Select the UV as shown in the screenshot.

3. Press "Rebake" in the script and wait for about 5 minutes (the time depends on the computer you're using).

4. Delete the old UV.
5. Perform a cleanup.
