Transparent Background Capture in ScreenshotKit

Usage

using DaCruz.ScreenshotKit;

var alphaSource = ScreenshotCapture.TransparentAlphaSource.Hybrid;
var result = ScreenshotCapture.CapturePostProcessTransparent(sourceCamera, settings, alphaSource);

// Or with mattes alongside:
var fullResult = ScreenshotCapture.CapturePostProcessTransparentWithMattes(
    sourceCamera, settings, alphaSource
);

Alpha sources

TransparentAlphaSource has three values, matching the window’s Alpha Source dropdown:

Value	Alpha comes from
`CryptomatteOnly`	The Cryptomatte alpha pass. Sharp geometry edges, no bloom in alpha.
`PostProcessOnly`	A dual render over black and white; captures bloom and flares in alpha.
`Hybrid`	`max(Cryptomatte, PostProcess)`: sharp edges plus post-process glow.

The setting field on ScreenshotSettings is ppAlphaSource if you would rather pull it from the asset.

If Cryptomatte alpha is not available on the active render pipeline, Hybrid falls back to PostProcessOnly and logs a warning.

Save as PNG, TGA, or EXR; JPEG has no alpha channel.
