Scale dependent transparencies

[JorgeLagos1]

 I would like to set scale dependent transparencies. In other words, I would like to have my polygons displaying solid from far away but increase the transparency as the user zooms closer in.  Currently, I am forced to add the same layer several times and set different tranparencies for each one.

Thanks

Brilliant idea!


In this example the transparans should be increased between 1:50 000 to 1:1000.
