I have 2 Walls and a lamp in between them. The walls stays close to the floor, there is nothing between but the light is shinning through which is completely nonsense. How to prevent this behavior?

  • $\begingroup$ It probably won't look very good, and if you start doing it to all your lamps there will be a performance hit - but you can try giving each lamp a shadow. The spectacular on your ground plane still might look wierd behind the wall, but at least there will be no direct light shining on it. $\endgroup$ Apr 1, 2019 at 18:08
  • $\begingroup$ Thank you, i tried that right now. But if i do that (hopefully i did it right) it looks like there is no specularity at all, so wouldnt it be better to turn off specularity in this case? $\endgroup$

  • $\begingroup$ My solution is to either lay a duplicate ground (plane) a little above the original and either break it in 2 or trim or shape it's adjoining edge where the ight is leaking through. Place that duplicate in a separate layer and set the lamp(s) to "This Layer Only", Duplicate the main lamp from the 1st layer into the 2nd so the ambient lighting is identical. I'll drop a short video up on Dropbox. It's too large for here when GIF'd. Note - almost all of my rendering is in OpenGL and that can sometimes appear different to Blender Render and certainly will with Cycles. $\endgroup$
