Difficult to see if the others are distorted or not, seems to be just to be a homogeneous color where no distortion could be seen. This is probably related to what I'm seeing with the runway shader effect. I haven't touched either shader code for at least 6 months, so... something has somehow happened to the process creating the runway uv-mapping (normals? tangents?) which screws up the shaders specifically on runways. Now, since not everyone sees it, I first suspected some hardware specific quirk, but James is running pretty much the same hardware and apparently doesn't get any problems. Thus, the next culprit which I can think of is that I compile under Linux against OSG 3.0.1 rather than latest, and it appears that OSG specifics can also throw the other shaders off track as reported during the last days. So my current suspicion is that we're dealing with some OSG change here where dependence on OSG devel versions has somehow crept into the FG/SG code and leads to problems with runways when compiling against OSG last stable. Beats me why this is runway specific, but I would observe if it goes away once the OSG issues are tackled. > 2.

Rayleigh, Mie and density factors should now be controlled by Basic Weather as well as Advanced Weather after Stuart's work on making Basic Weather run ALS better - so as far as I know the sliders should in fact be obsolete. Maybe Stuart can comment? Definitely they should be non-functional (or even absent) when Advanced Weather is running. * Thorsten ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
