Trouble Shoot: Fuzzy outlines around PNG and PSD Files in Storyboard Pro

So I Imported both PNG and PSD files in 3D mode on Storyboard pro. and all the images have fuzzy outlines and trying to figure out how to get rid of them…

I added a blue sky to hopefully hide them but they are still noticeable and distracting in certain angles.

I had this issue on toon boom and was able to fix that but don’t know to do it in storyboard pro.

Appreciate any help.

hopefully the image was able to upload.
