Hello I get most of the shaders working on my older card with changing the parts where gl_FrontFacing is used (see my last posting to "New effects on OSX" here).
In terrain-default/model-default/default/reflect.frag I changed "if (!gl_FrontFacing)" to "if (n.z < 0.000001)" and almost everything seems to work. Of course this is related to some problems with my ATI driver but maybe this can solve also some other card/driver shader problems (i.e. for FG 2.0.0 osx version where some shaders are disabled)? Can you please test this lines for other driver/cards and give some feedback? Does not using "gl_FrontFacing" also increase performance? Thank you for your answers. -Y. ------------------------------------------------------------------------------ _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
