Why is this happining? texture stretching

[hectorthedog]

Hi, I am bringing a simple cube from blender, i have unwrapped it various times and I always get this issue when I export the textures. any help, please? i know my uvs are not stretched, I perfectly subdivided this cube. How do I get rid of that stretched side bit on the texture, I have never seen this before on a texture. Thanks

Hello @hectorthedog ,

Thanks for the message.

The stripes in your exported maps are simply Dilation. The Dilation (or padding) is an automatic process at export that uses the last pixels at the border of UV islands and expand them in the empty spaces of the UV map. It prevents artifacts and are especially important when working with mipmaps.

It shouldn't be visible on your mesh after applying the textures, and I even strongly advise you to keep a certain level of Dilation on all your textures.
