Ok, theres a pic that im rendering, and it has 2 problems with it.

1. The mirror that i'm using reflects stuff, thankfully, but it also has a very bright "shine" to it. Thus, anything that is reflected is almost overpowered, and the mirror almost looks like its glowing.
   what Surface settings do i need to get a "flat" mirror that isnt so bright?

2. When saving as a PNG file, i try putting the pic together in Photoshop.
   Unfortunately, whatever is layered onto another image has some sort of white line outlining it.
   how do i get rid of it/fix it?

will be attaching example pics soon.
