As said in title: is there a way to apply a texture to opacity so I can see through one object according to the black & white image i use as a map?

Thank you,

The only material that currently supports this is the General Material. We will have this capability for other materials in the future.

So what should I do with it to achieve my aim?
Where should I place my texture?
