transparent background in blender
i have been trying to import an image (png) with a transparent background into blender as a plane. all gos well until i unselect the plane then there is a blackish gradded border around the image. the image works fine in all other applications just not with blender.
i have fooled with all the settings i can with gimp but i'm stuck.
if anyone can help
thanks very much

RE: transparent background in blender
thanks for your reply, things are even worse than i thought, i'm not sure how well you know blender but i am using blender to do some camera tracking. last year i did some with great success (it was my first time using gimp) i am a corel user normally but the version of corel i have won't save transparent backgrounds, only with gif and the quality is not too good. i also can't seem to get the latest version of blender to render the transparent. i am going to try an earlier version of blender.
i will add to this thread when i get things more honed down
thanks again

RE: transparent background in blender
About a week ago I was working on an image using Gimp 2.8.2, removed the background leaving transparency.
I open the saved png in another graphics app - fotoxx (linux) to do some distorts and found the background was restored.
Assumed my fault, tried again, same result. Just got round to another look at it, the same process in gimp 2.6 works fine. What was the difference.

That 'save colors from transparent pixels' is now a default setting, fotoxx just ignores the transparency. I wonder if Blender is the same.
Unticked that and now works as expected.
