Problems with UV unwrapping in Substance Painter 3D.

Hello! There is a problem. There are no problems when creating UV mapping in Blender, I checked. On the right in the picture you can see that the UV scan of the light gray contour is incorrect and blurry. I redid the UV unwrapping in Blender several times, turned off the Auto-Unwrap checkbox...
I will be glad to solve the problem

I did, sorry for the time in response. We can see in your first picture that the UVs are already stretched, therefore the texturing will be stretched too.

 

 

You need to make sure the UVs respect the 3D object proportions in order to avoid stretching. In addition, considering how crowded the UV map looks, I advise you to use a UDIM workflow. You'll avoid too small UV islands, and with that artifacts.

No, they're not. But I but I found differences between the UVs from Blender and Substance. Here are the last maps.

Hi @Sveta29656096ousl,

 

Thank you for the message.

 

Do you have by any chance overlapping UVs? Can you show us a screenshot of the entire UV map?

 

Let me know.
