VaM 1.x Make glass mirror opaque

[Vreejack]

The standard glass can be set up as a pretty good mirror, but it retains one problem: I can't figure out how to make it opaque, so you can see whatever is behind it, like the wall.

Am I missing a setting? Or must I create a custom rectangle to block the back of the glass?

Do you want to make it 100% opaque? You can use the ReflectiveSlate for that instead of the glass.

Reflection opacity at 0 to make it just glass (transparent with minimal reflection) 1.00 to make it a full mirror (full reflection).
You need light atoms too, global lighting is not enough.
