Unity Light choppiness? (Video)

Hi, I just got this problem on Unity Android. I must have changed something since it worked earlier today. I have a spotlight with a lightcookie attached as a children of the camera. It should move smoothly along with the camera. It works great in the editor, but when I build to Android it begins to be choppy and laggy. Here is a video that shows the choppyness (look at the background light)


Thanks, Andreas.

Looks like it’s vertex lit. If you increase the resolution of the background mesh, the effect would become less noticeable.

Or consider using a pixel lit shader.
