This is odd. I have a transparent texture mapped onto a plane. For some reason, when light hits the very top of of the plane it’s creating a solid horizontal white line - it’s almost like a specular highlight. If I remove the light from the scene it no longer renders that white line. It kind of comes and goes based on the position of the light and the model. This is a transparent part of the image, so there shouldn’t be anything rendering there.
Deferred and Legacy Deferred don’t have the white line at the top, BUT there is one on the bottom, which is peculiar. That could be because the texture is running all the way to the bottom of the screen, but I’m still not sure why light would be slamming the edge of a plane like that.
