PNG transparency problem / best way for transparency

Hi all

I am currently learning how to do UV unwrapping in Blender. I have been making PNG -24 files in Photoshop that have transparency, but I get annoying white edges (marked:)


How do I get rid of them? I’ve tried clipping, power of two dimensions, everything.

Related, what is ‘the best way’ of transparency in Blender? Should I be using another file type?

Cheers!

Also, try the premultiply alpha option. It can help with the alpha not seeming to fade out correctly.

Nice, thanks for the help!

Also, I have another solution too (after a great deal of internet searching and wall /head banging):

Set this option (in Photoshop):


It seems to sort things out.

In other words, the image contained these borders?

Photoshop does apparently have problems with PNG transparencies from my research.

It was strange, all layers in the original were cleaned so there was no pixels in Photoshop. I read that there was a setting on export that disables the matte but on investigation could not be set (it was greyed out for me). I then remembered that I saw the above option for matte removal and the problem appeared to go.
