I'm working on an project where I need to import some graphics that I created. I'm able to import them fine using the Import Images as Planes plugin.
They look totally fine when in the Material viewport shading type:
However, as soon as I go to render it out, I get these strange speckles along the sides and top:
I'm using Blender 2.76, hash 477078b and from what I can tell it's the image bleeding over the edge of the plane to the other side, but I have no idea how to fix that.
Does anyone know what's causing this and how I could fix it?
