Opacity Maps in Marmoset Toolbag 2

[Deleted User]

How do I use a simple greyscale map for opacity? What slot/section is the place for it? I have a gun w/ a scope and want to simply make the scope refractive.

you put it in the alpha channel of your diffuse texture.

For this you're best off making the lens of the scope a separate object, applying a new material to it and using additive blending.
