Why does ProcessScreenshots write all alpha to 255? And, why is alpha inverted otherwise?

Hey there! I’ve got a Jira ticket written up for this issue and the details should populate at Unreal Engine Issues and Bug Tracker (UE\-313955) in the next day or two. Is there anything else you need on this issue for the time being?

It’s good to have a bug. It would be good to fix this.

I want to make sure that in the bug the reader understands the current incorrect behavior and correct expected behavior.

> The output screenshot’s alpha should is be uniformly 255, even though nothing was rendered in the pixels that weren’t the cube

The expected behavior is that the screenshot alpha should be 0 for pixels that were not the cube.

Thanks for catching that! I’ve updated the ticket.
