Erik That would be a brilliant solution because then you could just add some emmisive white and red and 'bingo' you've switched the panel lights on :-) The other ways I've looked at are using extra polys + textures to switch between emmissive levels but the polycounts get nightmareish (My instruments are already quite poly heavy but they do look nice ;) ) (says prayers for an understanding developer ;-) ) Dave Martin ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d

The default C172 electrical system is pretty extensive and has all these sorts of switches layed out. You just need to connect a panel click (or real hardware) and it should all work. We even have the circuit breakers modeled properly for the C172. There are some limitations to the electrical system in terms of modeling current draw (which is fixable), but it's quite flexible for laying out a variety of power sources, buses, switches, circuit breakers, etc. You can layout an electrical system so all the right bits go dark when a particular switch is flipped, or circuit breaker trips.
