Hi,
CreateScreenshotUsingRenderTarget gives different result from the canvas and CreateScreenshot.
Playground: https://www.babylonjs-playground.com/#L2RPV8
The wireframe clone is hidden by setting layerMask, but still appears in the image created by CreateScreenshotUsingRenderTarget.
CreateScreenshot works. Also, CreateScreenshotUsingRenderTarget of Babylon.js 2.5 works.
