[ka-Map-users] background transparency of a layer group

[Manuel de la Calle Alonso]

Hi list, I´m triying to put some layers in KaMap and I have a problem 
with the layer transparency. When I asign a group to a layer, in this 
moment, this layer it´s not transparent. If I put the transparency level 
near 0, I don´t see the layer. How can I put the background of all layer 
groups as transparent??

My map file is:

        NAME "nurb"
        TYPE POLYGON
