Hi there,
it's an old topic about undesirable pixels around PNGs + alpha that may happens sometimes when loading files outside TVPaint.
In TVP, I'm used to export 32bits PNGs with No PreMultiply and I've been quite lucky so far.
But when I import my files into a tool using a game engine, depending how the colors + alpha are, it's not accurate to say the least.
It looks like every drawing package have its own way for saving PNGs and alpha processing be different...
I tried a lot of things tweaking backgrounds, colors, masks,... Nothing works.
TVP users: what is your workflow to get rid of this edges or at least to soften them?
I know people using SuperPNG but it only works for a well-known tool I don't use :]
TVP Dev: aside FX stack, we don't have RGBA channels, any solutions to prevent this?
Pixelated edges around files such as PNGs or TGAs
Re: Pixelated edges around files such as PNGs or TGAs
Oh yes, that is an issue in all programs I use.
My usual workflow is TVP to Moho or FinalCut. In Moho it depends on brightness of top and bottom colour. If I animate white clouds in TVP to put them on a bright blue sky in Moho, I use "no premultiply". Some bright clour on the same colour in Moho: "no premultiply" as well. Anything with a black outline is "premultiply".

Re: Pixelated edges around files such as PNGs or TGAs
I tried to export to Premultiply too to spot differences, but it always makes the edges worse like an intentional outline, so NoPremultiply is rather a better choice to export (for me).
To be honest, even if I don't spot differences, I wonder if the choice of the background "None, Color or Check" has impact on alpha when exporting![Question :?:](./images/smilies/icon_question.gif)
