I'm new to Blender. I've got a scene, I downloaded from an Internet forum about a year ago, but light isn't working.

If I create a new file, add a mesh and shine a light on it I get light.

When I follow the same process in the scene I want to light the spotlight has no effect.

Any ideas?

lighting panel

Thanks to @Timaroberts it appears the scene is upside down or something.

When I move the lamp underneath the plane and rotate it the scene lights as expected.

  • $\begingroup$ If it is on layer one you need to turn layer one on or move the light to layer one. The layers are represented by the grids at the bottom of the window. If a square is greyed out it is off. $\endgroup$ – Dontwalk Jan 19 '16 at 18:25
  • $\begingroup$ Are the layers your light and mesh live on, both being rendered in the 'Render Layers' under the 'Scene Tab' in the 'Properties Panel'? $\endgroup$ – dval Jan 19 '16 at 18:35
  • $\begingroup$ Did you create the light in Blender internal, or game? If so, it may not work in cycles. The same goes for materials. $\endgroup$ – Uncle Snail Jan 19 '16 at 20:00

It looks to me like the energy settings of the lamp, in wireframe you won't see the lighting, and your rendered viewport looks normal for a single spot at default values. Change the lamp's strength to a higher value, or you may use a plane with an emission material and you will see your scene much more clearly.enter image description here

  • $\begingroup$ thanks for the detailed answer. I added the emission plane and I got the same result until I moved it below my plane. Then I noticed if I move the lamp below my plane and rotate it to shine up it works as expected. It seems my scene is upside down or inverted or something... $\endgroup$ – David Silva Smith Jan 19 '16 at 20:06
