Underlying is the texture I'm writing to. This is what I got so far, but it doesn't give the same result as when AlphaBlendEnable = TRUE. What formula does default alpha blend in HLSL use?

alpha betas,
Alpha testing occurs first and when the software passes that, beta testing can then be undertaken. If a software fails alpha testing, changes are done and it repeats the tests until the software passes. So to answer your question, an Alpha and Beta release can be considered the 'testable deployed artifact' that you are currently developing.
As per suggestion I'm splitting How do I create a closed beta on the App Store? up. Can I upload the game I'm developing to Steam as a closed beta, so I could generate a couple of keys/tokens for my That said, the scheme you mentioned is quite common for released games. 1.0 will typically be the gold master, and patches will start from there: 1.1, 1.2. It'as also used in pre-release customer versions such as private or open betas. For games in development I've rarely seen this system used.
Pre-multiplied Alpha blending uses a different formula: result = foreground + (1 - foreground.alpha) * background It's so-named because the multiplication of the first term by foreground.alpha has been baked-in ahead of time. So you can see, anything we can do with conventional alpha blending, we can do with pre-multiplied alpha blending. You .

However, when this method is used with transparent textures that do not have premultiplied alpha, the resulting mip levels tend to have black outlines at the transparency edges. For instance, this PNG texture, loaded through WIC and processed with GenerateMips, produces mipmaps with edge pixels that are way too dark:This is a fairly common approach to transparency in games that use deferred shading. Proper transparency doesn't work well at all with deferred shading, since only one surface's data (depth, normal vector, color, etc.) can be stored at each pixel, and proper transparency involves multiple surfaces overlapping at a pixel, each requiring independent lighting.alpha betas Stereo-typically invisibility is conveyed by making characters half transparent. Now to do that, you need to add 0.5 to the sprite's alpha during blitting. If the sprite already has premultiplied alpha, that can't be done. So I think doing premutliplied alpha is a kind of premature optimization, which can shot one into leg and limit his toolset.
