Now default texture has been replaced by your custom texture.

Dimming params

You can set the dimming parameters that control the light emission. As example, insert your KT 76A as follows:

    <x-m> YourValue </x-m>
    <y-m> YourValue </y-m>
    <z-m> YourValue </z-m>

Now controls/instruments/transponder-light is controlling the light emission of the KT 76A.
