I'm attempting to shine a spot light through text that has been cut out of a plane. The effect works pretty well, but some of the light from the spot light that is behind the plane shows through as seen in this picture:

enter image description here

The plane uses default settings and has no material or texture associated with it, though adding a solid black material has no effect on the render.

Lamp is set to Spot, Buffer Shadow, Halo, Step=1, Distance=10, Size=130. Other settings are pretty much the default settings.

I've been playing with this for hours and can't seem to figure this one out. Any ideas?

  • $\begingroup$ Ray shadow does not give the right effect. Here is a link to a dropbox folder containing the .blend file. dropbox.com/sh/05831purpzk4x62/AAD4t7fO7uIvjs7sqrwAXnmZa?dl=0 $\endgroup$ – Aaron Oct 28 '15 at 1:35

I think is the blocking object, it's 2D. Try to get another one starting from a 3d even slightly extruded plane (extruding your gives me weird results), carving out the text. Then you might need a slightly more powerful (energy) spot, but in this way I got it working.

  • $\begingroup$ just add a solidify modifier. $\endgroup$ – user1853 Oct 28 '15 at 16:08
  • $\begingroup$ Looks like both of these solutions will work, but the modifier may be the easiest for my case. Thanks! $\endgroup$ – Aaron Oct 28 '15 at 22:10
  • $\begingroup$ Just tested. Modifier worked great and was a quick solution. $\endgroup$ – Aaron Oct 28 '15 at 22:29
  • $\begingroup$ @Aaron you should accept this answer (click the green checkmark) if it was the right answer. $\endgroup$ – Bojidar Marinov Nov 27 '15 at 14:07
  • $\begingroup$ No, I think he already chose the other one, using the solidify modifier to get the same result (i remember that answer) but now... is no more? weird. $\endgroup$ – m.ardito Nov 27 '15 at 14:08
