I am learning Blender by play around with the default startup scene, where there is a cube, a camera, and a point light source.
I then only did one thing: I increased
Material -> Specular -> Intensity from 0.5 to 1.0.
Then I render the scene. Although the material preview shows some specularity, the rendered image doesn't show any specularity.
Why is this, and how may I fix it?
