Robbo,
I just went through the process of adding this "texture" to the A380
after reading the source code, for when you are taxiing around an
airport.
The output texture "file" is in essence a virtual file. So the texture
is created in memory and given a path reference (it's never actually
persisted to the file system),
So when you add the instrument to the aircraft, you must exactly use
the virtual path, I never knew this was possible, it's a simple but
highly effective idea.

All the data continuously generated in your IT infrastructure contains a
definitive record of customers, application performance, security
threats, fraudulent activity and more. Splunk takes this data and makes
sense of it. Business sense. IT sense. Common sense.
