Modded Graphics have white lines around them

[ZestyLemons]

Here's the gun I drew and modded in:



It has awful white lines around the stock, trigger guard, and sight. I can't get rid of them. It's 64x64, and its a transparent .PNG


Here's the default shotgun for reference:


When I used the exact same graphic and replaced my modded shotgun with that one, it also had white lines:


Some notes:
- There are no white pixels in my photoshop file.
- Drawing anything has these white lines appear. Giant black sphere? White lines. Massive expletive text? White lines again.
- I'm using Photoshop CS5 currently.
- All three graphics are 64 by 64 pixels
- The two I tried to mod are .PNGs


What am I doing wrong?

I haven't personally encountered this problem but I remember reading about similar thing here, with a possible fix for it (?)

It might be of help! it might not =P
And slightly beside the point but that shotgun of yours looks like it could pack some punch with that massive barrel, I like it

Make a background that covers entire texture and set its opacity to 1%, you can also use alpha channel for that.

Found a slightly nicer solution, added a black matte in Photoshop when I save the texture.


Thanks for the advice though, I'll try those too and see if it's any better. Maybe I should bug report this?

Its not a bug thats how unity engine works

[ZestyLemons]

Not sure how a completely transparent pixel not being transparent isn't a bug. Are Tynan's sprites done the same way with 1% background opacity/matte?

[mrofa]

No his spritest are made with full color background and alpha channel
