I just created a 3D model of a barrel and UV unwarped. That thing below is the screenshot of the UV image editor.
Then I clicked new button below the UV image editors window and gave a name barrel and unchecked the alpha option, and selected blank to color fill option then clicked ok. then I changed the viewport to texture mode. I can't see the color grid texture on my object. Image below.
i am using blender 2.78n thanks in advance for any help.
