There's lines on my seams

[Ilya Orchakov]

Hello everyone!
Here's my problem

There is those red lines on seams of a model, and I don't know how to get rid of them.

I guess, it somehow related to the first layer folder, which texture is red. And I use different models in same position, but with same material.

Even if I hide first red layer, you can still clearly see those blank lines on seams. How do I solve this? It is serious problem for me.

Even putting them in Blender doesn't help.
I beg you guys, please help.
I think this problem applies to texture due to its material wich contains multiple models in it. But how to fill those blanks?
Can not upload my file here  -_- . So I hope you understood my problem, and will try to find solution

Hello @Ilya Orchakov,

Thanks for the message.

We can even see the lines on the UVs in the 2D view. It looks a bit like Padding issues, but I am not sure that's the problem here. What was your workflow to select these areas? Would you agree to share your files, so I can take a deeper look? 

Keep me updated.

Hello! And thank you very much!
As you said, the broblem is in that padding thing.

I changed this two options, and now it works as I want to.

As you can see, it fills properly now, without any lines on seams

The problem is solved.
Thank you again!
