Re: [Flightgear-devel] Shader question
There is also another approach to creating normal maps, using a detailed, high polygon count model of the object, from which you extract the normals and map them to the low polygon object which is used in the game. A nice tutorial for blender can be found here : http://blenderartists.org/forum/showthread.php?t=138194 These are very generic instructions for normal map baking, I didn't try the FG shader yet, so I presume this may need some tweaking, specially regarding the normal space to be used. See http://wiki.blender.org/index.php/Doc:Manual/Render/Bake for more details about normal space. This normal map shader work will be a huge step ahead for image quality in FG, congratulations !

Re: [Flightgear-devel] Shader question
Hi, The shader is great! Though I have to admit it really works great on a middle to far distance, as the buildings don't show any windows, walls etc. Would be great it would support nightlighting as well. (Switching between emissive nightlighted and daylighted textures) So we can get rid of those ugly lightpoints But as an aircraft developer I'm really happy to see that it works on any 3d-object easily as well: http://www.hoerbird.net/fredswonderfullnewbumpmapshader.jpg Now I have to learn to make normalmaps! :-) Thanks to Fred!

[Flightgear-devel] Shader question
Hi Tim, is there a way to have the value of an uniform updated every frame by the value of a live property ? I used : parameters sun-angleuse/sim/time/sun-angle-rad/use/sun-angle /parameters and then, in pass uniform namesun_angle/name typefloat/type valueusesun-angle/use/value /uniform According to README.effect, the value should dynamically change but my shader variable stay at 0.0. The readme also says [NOT IMPLEMENTED YET], but it is unclear to me what in not implemented : the copy of a value from the global property tree to a uniform, or the copy from a local property, or both ?
