Premultiplied looks at what you're actually compositing in place of alpha. In After Effects, for example, you might have your background set to blue, despite it being transparent. In this instance, when rendering, the falloff to transparency goes to blue before hitting 0 percent opacity (the pixels that are between 1 and 99 percent transparent ....
Posted March 12, 2020 (edited) In case you use premultipliedalpha in png textures, specify it for pixi: dig out which baseTexture it uses and specify "mySpineResource.spineAtlas.pages [0].baseTexture.pmaMode = PIXI.ALPHA_MODES.PMA" We added this feature to pixi but didn't propagate it to pixi-spine.

Basically, any alpha below 1.0 will get premultiplied with a number less than 1 and thus become smaller (and result in a darker color). Ultimately, multiplying an alpha of 0 means the rest of the color channels will also become 0. Those three less multiplication operations done per pixel means it renders/composites a little bit faster.

Bleh, this is an acknowledged issue as far as the canvas spec is concerned. It notes: Due to the lossy nature of converting to and from premultiplied alpha color values, pixels that have just been set using putImageData() might be returned to an equivalent getImageData() as different values.

The gist of it is this: PREMULTIPLIEDALPHA BLENDING is a fast, standard transparency blending algorithm for game graphics. But it requires a specific math operation (a multiplication step per color) to be done ahead of time. Saving images with "premultipliedalpha" means you're preparing an image to be blended using the above algorithm.
The Unity Standard Particle Shaders are built-in shaders that enable you to render a variety of Particle System A component that simulates fluid entities such as liquids, clouds and flames by generating and animating large numbers of small 2D images in the scene. More info See in Glossary effects. These shaders provide various particle-specific features that aren't available with the.

Was your input atlas texture exported with premultipliedalpha (PMA) or straight alpha (bleed)? Could you perhaps show the (working) Material settings that you used with the Spine/Skeleton Tint shader? In case you haven't already looked at it, this is the relevant original shader code:.
This code is converting from premultipliedalpha:. Expanding one of the assignments by substituting for divAlpha:. var r = (byte) (color.R*(0xff00/color.A) >> 8); which on rearrangement of the multiplicative terms becomes.

So basically you need something like the following code instead. You can also change blending to normal SrcAlpha OneMinusSrcAlpha blend mode, otherwise you need to premultiply the alpha value to the RGB color value. // Blend One OneMinusSrcAlpha // change this line. Blend SrcAlpha OneMinusSrcAlpha // to this line.

What I would like to know is if this is a known behavior of Spine. Is there a workaround for this issue without switching to premultiplied alpha? I find it curious that LibGDX is very much against using premultiplied alpha and Spine is the polar opposite. Reproduction Steps: *Create an animation that fades from transparent to opaque.

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 same as alpha blend in URP.

1) Textures with sudden changes in colour and alpha at the same place - e.g. an opaque white circle with a low-alpha black drop-shadow. These can still exhibit nasty fringes. 2) You can't use clever premultipliedalpha tricks, such as regular alpha blending and additive blending in a the same draw call.
