Engine not moving ship [1.3]

[UbuntuLinuxKing]

So,

I made a modded engine based off of the Mainsail. It works great! However, when I change the model to anything other than the Mainsail, the engine proceeds to:

• Turn on
• Make noise
• Consume fuel
• Produce no movement or drive plume of any kind

No matter what I do, after changing the model, the engine refuses to show any sign of thrust or a drive plume. Right clicking shows that it is producing the correct amount of thrust, but it isn't moving the craft. It can't be a thrust-weight issue, because the drive produces 50,000 kn of thrust against a 3.75m fuel tank and a 1-2 Command Pod, both of which are stock. The debug console throws exception: nullreferenceexception object reference not set to an instance of an object over and over. Does that have anything to do with it?

Anyone know how to fix this?

My first guess would be that the model that your replacing the mainsail with has a different thrust transform name - the "thrustVectorTransformName = " in the config file.

A good tool to find the internals of a model in game is:

Did you add a thrust transformer to your model ?
