I’m doing some animations that will be integrated on a website and outputting my objects on PNG with Alpha Channel. What happens is that the background area, that should come out completely transparent is turning out with a very slight grey. This makes a square visible around the image. A very dull one, but it’s there.
Anyone knows why this happens and how to fix it in Blender? Of course I could always run a batch in Photoshop to select that and delete, but that’s a far from perfect solution.
