Shading can be disabled globally by choosing View > Render Options > Lighting or by
choosing Lighting in the Render pop-up menu in the status bar. (Make sure there is no
checkmark beside the menu item.) Shading can also be disabled for a specific object in
the Lighting section of an object’s Properties Inspector. For more about disabling
lighting/shading, see Disabling Lighting.
Shading disabled globally Shading disabled on floor object
With spot lights, enabling shadows but disabling shading can create a seemingly strange
result where the shadow is suddenly cut off because it has exceeded the scope of the
light cone. Because the shading effect of the light cone is turned off, the shadow edge
looks unnatural.
To correct such an occurrence, increase the Cone Angle in the Light Inspector.
Disabling Shadows
Rendering shadows can significantly impact playback performance, so you might want
to temporarily disable shadows to improve playback speed while working on other aspects
of your project.
To disable rendering of shadows
µ
From the Render pop-up menu in the status bar, choose Shadows (or press
