Plane Light not working

Hi there! I have a little problem and I was hoping that someone could help me with it. In short, the plane light that I created is not emitting any light, regardless of intensity that I set for it. On the other hand my sphere light is working just fine. Anyway, I’m wondering what the problem might be. Any ideas?


Two quick thoughts:

  • make sure the light is facing the right direction, downward not upward
  • the intensity units affect how high you have to set the value to get sensible brightness. Default units often need very large values.

It still doesn’t work. Not only that vray is extremely slow when this light is enabled

Everything works now. Turns out all I had to do is reinstall vray and copy the model into a different file.
Thanks for your input!
