Description

When using the new Draw Material to Render Target function in conjunction with a Material using a masked opacity channel, the render texture is inverted. See attached images for reference.

As a note, a workaround is to add a OneMinus to the parented 'passthrough' material which will invert the Opacity channel and render the texture correctly.

Steps to Reproduce

1. Open attached project.
2. Press PIE

Outcome The alpha opacity mask renders inverted/flipped.

Expected The opacity mask renders how the Alpha channel displays within the texture.
