Select a node to adjust its parameters.

Inputs

foreground
background
opacity_map (optional) : Optional per-pixel opacity multiplier.

Parameters

Parameter	Type	Default	Range	Description
`mode` Mode	enum	copy		Blend mode for combining foreground and background. `copy` : Use the foreground color as the blended color before opacity is applied. `multiply` : Darken by multiplying background and foreground colors. `screen` : Brighten by inverting, multiplying, and inverting back. `overlay` : Multiply dark background areas and screen light background areas. `add` : Add Foreground to Background. The final output is limited to 0-1. `subtract` : Subtract Foreground from Background. The final output is limited to 0-1. `add_sub` : Add or subtract based on whether the foreground is above or below mid gray. `min` : Use the darker value from Background and Foreground. `max` : Use the brighter value from Background and Foreground. `divide` : Divide Background by Foreground. The final output is limited to 0-1. `soft_light` : Apply a soft contrast blend using the foreground as the light source.
`alpha_blending` Alpha blending	enum	use_source_alpha		How the alpha channels of Foreground and Background are interpreted. `use_source_alpha` : Interpolate the blend result with Background using Opacity multiplied by Foreground alpha. `ignore_alpha` : Interpolate the blend result with Background using Opacity alone. `straight_alpha_blending` : Composite Foreground and Background as straight-alpha colors. `premultiplied_alpha_blending` : Composite Foreground and Background as premultiplied-alpha colors. Only applies to Copy mode.
`opacity` Opacity	float	1	0 to 1	Global opacity. Multiplied by Opacity Map when one is connected.
