While working on another mod I ran across a method named SetOpacity. I couldn't resist – had to see if I could make this work. It does! Well sort of. Vessels are partially visible against the near field but are invisible (at zero opacity).

Instructions:

• Add the “Surface mounted cloaking device” under the Utility tab to your vessel
• Fade time and maximum fade can be set in the editor or in flight
• In flight toggle the Cloak on/off with the right click menu
• The cloak part its self can be set to leave its self uncloaked – or not

Known bugs:

• Fairings and solar panels don't uncloak when broken off the vessel
• Strut, fuel line end caps and cloak slug don't disappear until full cloak
• Some funny interactions if more than one cloak device on the same vessel - work around - don't activate more than one device at a time per vessel

Notes:

• Does not hide vessel from BDArmory radars
• Some oddities with visibility and the near field (area close to the craft)
• If you set the cloak device to cloak its self make sure to set the “Cloak Off” to an action group other wise you may not be able to find the part to right click again.
• I haven't balanced this – it should probably use a lot more electricity. Can be easily changed by editing the config file.
• Device its self doesn't disapear untill full cloak - Due to new shaders?
