This happens with a simple sphere object in my scene with just 1 directional light. I apply standard shader with just an Albedo colour and 0.5 metallic->smoothness (so it’s quite specular) …
in the top left corner of my screen (which is the direction the light is coming from) it is like all the objects are passing through a quarter circle of blinding light… they go to white… there is sharp-ish line when they pass out of this quite small zone and start looking normal again…
its an orthogonal camera if that could be making a difference… all baking etc is disabled in the scene i think.
It only happens on device… it looks fine in the unity editor…
(red arrow shows the problem area on the image)
Any clues appreciated … Thanks.
At the top of Unity, go to Window - Lighting and decrease ambient intensity or Reflection intensity.
Try using a different shader to the standard shader - try one of the mobile shaders to see if that makes a difference.
