Premultiply-alpha
WebThe premultiply(_: alpha Info:) function uses a CGImage instance’s alpha information to determine whether an image contains premultiplied alpha. This function ensures that the top layer that the function passes to the composite operation contains premultiplied pixels.

I tried playing a different animation (in this case the Spine bow example provided on the Pixi examples) and it looks good, however, I don't know if that animation was exported as Premultiply Alpha or straight.
WebAug 7, 2013 · If you really require "premultiplied png" images, it is quite easy to DIY those in Photoshop: 1) import/open a png with normal transparency. 2) duplicate the original layer. 3) create a new fill layer and fill with either white or black, depending whether you need to premultiply with black or white. WebJul 22, 2024 · In Unity’s shader graph with HDRP, this means that the transparency is controlled by both color values and the alpha values. In URP, using the same shader graph setup, the premultiplied blend mode behaves differently than it does in HDRP, and the transparency is controlled only by the alpha values and premultiplied seems to act the …
