If you need to keep 2 sided faces. You can reverse the renders : 1/ select surface in the tool box 2/ select the faces you want to process 3/ Flip Normal in the menu (surface) -- Gerard _______________________________________________ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
