switch_default_blendmode(3) Arcan Lua API switch_default_blendmode(3) NAME switch_default_blendmode - Change the blend operation set as default on all new objects. SYNOPSIS nil switch_default_blendmode( int:mode ) DESCRIPTION Due to legacy and scripts dependent on now known buggy behaviour, the default blending mode is set to BLEND_FORCE . This means that regard- less of object opacity, everything will be drawn with blending enabled. This might be less performant on some GPU s when compared to the option of disabling blending for objects that are fully opaque and have no al- pha channel, which is refered to as BLEND_NORMAL . This function can be used to indicate that the script knows about the distinction or has other blending needs where a lot of force_image_blend calls can be avoided by changing the default to some other mode. NOTES 1 Specifying an invalid value for mode is a terminal state tran- sition. EXAMPLE function switch_default_blendmode0() switch_default_blendmode(BLEND_NORMAL) end SEE ALSO: vidsys April 2025 switch_default_blendmode(3)
