One way todo this is to always use the same size texture so as to be able to use glTexSubImage2D() to control the level of detail and mipmaping ourselves. Easiest todo this if the scenery is laid out so when you go to a lower level texture it covers 4 times the area and visa versa This works with SimGear's latitude adjusted tile 'bands' as they are broken into 8x8 sub grids :-) Norman _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
