  • $\begingroup$ What about having the light still in the scene and rotate everything around with camera? Motion is relative. You can workaround around this like that. The texture coordinates of lights does not follow the light's local transforms..that makes it very hard to do what you want - the solution won't be trivial if there is any at all. $\endgroup$ Commented Jul 1, 2016 at 19:34

    $\begingroup$ Also what about the UV project modifier to project a texture with round alpha with emission shader onto some geometry using the UV's $\endgroup$ Commented Jul 1, 2016 at 19:36
  • $\begingroup$ Still light and rotate the scene would be quite cumbersome to manage on a large scene, and would only ever work for one spot per scene unfortunately. The UV project modifier does make the desired effect but as I understand would only work in one object at a time, so it would also be a really cumbersome solution to light up a complex scene with lots of objects/lights. Thanks for the input though $\endgroup$ Commented Jul 1, 2016 at 23:42
