How to Adjust Vertices in Texture Paint

# Description

I’m using `Texture Paint` to create low-polygon models like `PSX`. However, because some vertices are shared with other vertices,

the model looks grainy when I move it. How can I fix this?

## About the Image

In the paint screen on the left, the gray color in the gaps of the red areas is likely the grainy surface on the corner on the right.

## What I Want to Know

Is this jaggedness caused by the vertex relationships?

Also, I don’t know how to fix it.

## What I’ve Tried

I’ve tried increasing the number of vertices and painting over the red area to check.

## About the `Blender` Files

The file containing the “sword” scene is the one in question.

“source” is the original data.

The polygon that’s selected in your screenshot is UV unwrapped to a single line. Part of it is exactly between the white and grey area.

Try moving a vertex a bit in the UV space. See attached video:
