Question by thaiscorpion · Sep 24, 2012 at 07:30 PM · spritesmoothtransparentpngorthello

How to fix smooth edges on sprites?

Hi, Im having problems getting my sprites with transparent backgrounds to have smooth edges. It seems as if the semi-transparent pixels near the borders have been converted to a full alpha color and makes the borders of the sprites look wierd.

Here is an example:

Original PNG file:

Screen shot from inside unity:

Is there a way to fix this? is there a problem with my PNG files? any help would be great!

PD:

Don´t know why but this PNG file looks fine in game:

Please do a more thorough search next time.

Here is a thread that is pretty in depth on why your problem happens, and how to solve it.

Have you tried setting the wrap mode of the texture to clamp? If that doesn't work, you may want to import the files as .PSD, or use the .TGA format ins$$anonymous$$d. I have a lot less issues with .TGA
