I am trying to learn Blender. While trying to render a subdivided plane with an image texture applied to it, the subdivision edges are not removed in the rendered result.

Kindly, advise, why these edges appear in the render.

  • $\begingroup$ Yes I agree it looks like they are part of the texture, try to open the image you are using and check if you see those lines outside of blender as well. $\endgroup$

  • $\begingroup$ the plane has no modifiers applied to it, the lines appearing during render are added to the texture during the uv unwrap because the plane has been subdivided before the uv unwrap $\endgroup$ Feb 25 '18 at 12:51

    $\begingroup$ the exported uv/unwrap image contains these lines $\endgroup$ Feb 25 '18 at 12:59

    $\begingroup$ Then i guess it's a problem of the image itself, you should use a tool like GIMP or Photoshop to delete those lines. $\endgroup$

It should be obvious that a texture with lines in it is going to render with those lines.

The Export UV Layout operator exports the UVs as lines so you can use it as a guide for texturing in external programs. (In your question you should not even need it, because you are just texturing a plane.)

plane and UVs exported UV layout
These images are the subdivided plane, its UVs and the image below is the exported UV layout.

In any event you must turn off the UV guide layer in your project (in whatever image editor you are using) before exporting the texture map to use back in blender.
