Substance painter Uv border generator won't work properly.

[Jamie26086581mzac]

When i unwrap a square plane in blender and use the full UV space, the Uv border generator won't works, if i slightly move UV inward, the generator works as usual.
Is there any better way to fix ?

Hi @Jamie26086581mzac,

Sorry for the delay in response.

Unfortunately, there isn't a better way to fix the issue. In fact, the generator is based on the Distance node from Substance 3D Designer and it doesn't work properly if there is no margin between the UV island and the border of the tile.

Some of our smart masks also depend on the Distance node, therefore I'd advise you to always keep a little margin between the UV islands and the border.

Best regards,
