Help with Substance painter

Nadra_Nagy

Hello guys, I was modeling an axe, the low poly was done on maya, then I sculpted the details on Zbrush
After uv unwrapping and exporting, I got this and the antialiasing was 8x8 could someone please help me??

That looks like the texel density being too low for that piece.

Thank you for your reply, but what is the texel density

Kanni3d

The amount of resolution your  UV islands receive per pixel (or scale of the islands to put it extremely simply). You can tell there's a mismatch in texel density as you have a sharp, crisp high res bake on the sides, but the middle problem area is blurry. 

That doesn't only seem to be the problem though, there's some gnarly stretching and distorting. You can select that problem uv island and give it another relax, and also should normalize the uv shells (which makes the islands the same scale/texel density).

feel free to attach your files like last time, and I'll take a look

As usual there for help Kanni, thank you do much, and you're right it wasn't the problem
I tried for several times to see what's the problem, and eventually it was cutting the UVs
