About exporting normal maps

Hi everyone,

I have unwrapped a model following the automated process.

I have checked the normal map in S3DP: it looks good and has black background between the islands.

After exporting it, I've got a different map having purple/blue color for background with artefacts.

The question is: is there any setting allowing to get black background between islands, like in S3DP, after export?

I think it would be better for visualization.

Thanks a lot!

Any idea maybe? Thanks.

Check your padding settings in Export >Settings> Global (and by individual texture set if overridden). The screenshot you show is expected when padding is set to dilation infinite.

Sure.

When I import the textures, the space between the islands is not black, it is purple as shown on the first screenshot I uploaded.

I have a black color in Substance 3D as shown in the second screenshot.

Dilation is infinite but when I change it to transparent it doesn't solve the issue.

Having no dilation and black right up to the UV edges can cause visible issues in the seams when rendering. To rephrase my question - what issue are you having by not having them black?
