Fred, My card supports GSLS 1.2 and OpenGL 2.1. What are the requirements for the new code? Maybe my card/driver i.e. does not support fake/hacks/overriding values like I found in some parts of new CVS SimGear code. When I test the shaders with shader building software they pass without problems. Of course, this is my personal experience and maybe realted only to one computer and one card in the world. Look, when I disable the shaders in the gui I disable all the shaders - but most of the shaders are working (lightning, reflection, landmass, cropping, clouds, particles etc.). My card/driver has just problems with "OpenGL fake" and passing effects/colrs etc. which comes directly from SimGear. Again, this is my personal interpretation. The shaders worked until some changes in april. So, maybe it is the only card/driver/computer in the world with this problem. I write this in respect of all the work you and others did. But just disabling the shaders because of a hack of an effect i probably do not need and which works only on "most" of the cards - this is not a solution for me. Personally. I dont know how many OSX/CVS contributors are here. But when I read some statistics I see that in the "world of OSX gaming" 25 percent of the mac users comes with my system actually. -Y. ------------------------------------------------------------------------------ _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
