This is a simple object with a coloring material. The image below has no material. I don't change any material parameters except the color. Why one of the faces look reflective?

  • $\begingroup$ Maybe it is not reflectivity but rather a problem of normals or bad shading, please share your file: blend-exchange.com $\endgroup$

The faces' textures are not changed and they are not reflective, merely shaded smooth. Just go to editmode, select and right-click the odd-looking faces, and click "shade flat" to fix them.

Welcome to BSE.

There are two issues with your model:

  1. Some of the normals are incorrect
  2. You have 80 sets of vertices that are overlapping eachother.

Please try the following steps:

  • Select your object and press Tab to enter edit mode.
  • Press A to select all vertices in the model.
  • Press M to remove any overlapping vertices.
  • Press Shift+N to recalculate your normals to the outside.

I had a look at your file and tried the above steps but unfortunately the issue persists. Therefore, I did the following:

  • Go to top view (Numpad 7)
  • In object mode, select your object
  • Press Shift+S > Cursor to Selected
  • Set your Pivot Point to 3D cursor (Shorcut: fullstop key)
  • Tab into edit mode.
  • Hover over the problematic geometry, and press L to select it:

  • Delete this geometry
  • Select the geometry opposite:

  • Press Shift+D to duplicate, then R to rotate and 180 for 180 degrees.

I believe this should leave you with what you want.

  • $\begingroup$ Thanks for your answer. I already merge the vertices. But the key of the problem is the shadow that another answer metions. $\endgroup$

  • $\begingroup$ Yeah I saw the answer from Bentley. I guess the problem was much more simple than I thought! Glad you got it fixed :) $\endgroup$

  • $\begingroup$ Simply check Auto smooth Normals under Object Data > Normals (green triangle icon). $\endgroup$
