BlendMode - Prototype Docs

BlendMode :: union

Determines how sprites/animations should blend with the background. The possible values are listed below.

Note that in most of Factorio it is assumed colors are in alpha pre-multiplied format, see FFF #172 - Blending and Rendering. Sprites get pre-multiplied when loaded, unless premul_alpha is set to false on the sprite/animation itself. Since generating mipmaps doesn't respect premul_alpha, lower mipmap levels will be in pre-multiplied format regardless.

Union members

`"normal"`	The result color is determined with the following formula: `Result = Active_RGB + Background_RGB * ( 1 - Active_Alpha )`. Note that this is alpha blending with an assumption that `Active_RGB` is already pre-multiplied with `Active_Alpha`.
`"additive"`	The result color is determined with the following formula: `Result = Active_RGB + Background_RGB`
`"additive-soft"`	The result color is determined with the following formula: `Result = Active_RGB * ( 1 - Background_RGB ) + Background_RGB`
`"multiplicative"`	The result color is determined with the following formula: `Result = Active_RGB * Background_RGB`
`"multiplicative-with-alpha"`	The result color is determined with the following formula: `Result = Active_RGB * Background_RGB * Active_Alpha + Background_RGB * ( 1 - Active_Alpha )`
`"overwrite"`	The result color is determined with the following formula: `Result = Active_RGBA or Background_RGBA`
