Something wrong with my UVs? (Blender and Substance)

Hi all,

 

I've importaed by uvwrapped mesh to Substance to get a decent wool texture for a turtleneck sweater. Almost everything is perfect on the UV Project mode, save for one thing: the center of the neck is curving instead of creating perfectly vertical/linear strips of wool. It does it correctly in triplanar mode but then the sides of the neck look strange. Here's my UV map and wireframe from Blender and a photo of UV Projection and Triplanar Projection as well for you. Rotating various parts of the UV and changing seam locations sadly did not help. Any ideas what the issue is?

Adjust the UV unwrap in Blender with the UV grid enabled so that you can keep the grid squares even and unstretched in the area you want. Blender has the tools to straighten and align the unwrapped mesh.

    Thanks for the feedback! This is my first time uvwrapping, so it makes sense that it might not be adequately done well. I'm gonna look into fixing the issue in Blender.

      In Blender's UV editing workspace at the top of the Image Editor view click new and choose Generated type UV grid.

      Then add a material and click on the Basecolor input for the PBR node and set it to use an image texture and choose the image texture you have just generated (if you didn't give the generated image a name it will be called "untitled"). Then set the viewport shading to material preview and you will be able to see the grid on your model as you unwrap. Simple example below just for demo:

       

      That will help you keep the seams, and any other parts, vertical/horizontal  where needed for your material to align.
