What I *read* wasn't what the code was actually doing, which explains all the confusion. Yes - thanks. I knew that you would come up with a proper solution. Bit more testing next time, Eh? This one, though, isn't fixed: 3. When a tank is empty, the tank is de-selected by fuel.nas. Thus the position of the fuel cock levers on the Spitfire panel do not necessarily reflect the state of the tank. This is really a metaphor collision. The notion of a tank selected as used by the fuel code and FDM isn't quite the same as that of position of the switch in the cockpit. Yes, quite. I'm still working on the best solution. (the magneto switches have traditionally had the same issue). Philosophically speaking, the property magneto should be a child of engine, while magneto-switch is a control property. Never mind, we don't need to go there, and I've worked up a good solution for the magneto switches in Nasal. It might be a better idea to define a different property to drive the fuel cock animation, and use a Nasal binding to synchronize this with the tank selected property only when it changes (basically: make the fuel cocks output only devices). At the moment this is the case, so when fuel.nas changes the selected state (and I understand why it needs to do this) the fuel cock levers are left behind, and no longer represent the state of selection of the tanks. An alternative is for the fuel cocks to accurately represent the state of selection. However, this would mean that they would move by themselves, which I don't particularly favour right now. I think a more complex solution might be necessary for proper realism. I can't quite see my way through this one yet. Anyway, thanks again for providing a proper solution to these problems Regards, Vivian ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d

In Oz, the AIP is available from www.Airservicesaustralia.com (a gov. body). They sell the info, but you can also get the PDF's online under online documents. To get electronic data, you have to buy it. The ERSA suppliments are also there. ERSA it managed by the RAAF/Airservices.

So, if you set a black color (0,0,0), it would stay black because 0 * X = 0. If you want your texture unmodified by the material color, set it to white (1,1,1). The only way to have a emissive effect on an object is to set an emissive material color ( for example white ) and modulate it with the texture : black in the texture - black on object, yellow in the texture - emissive yellow on the object. -Fred ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
