Development hell
Well it's time to address some errors (that is, the entire code). Today's topic: change of liveries.
It turns out that I programmed a function that builds the path where the skins are stored, that depend on a text file that defines the position of the skin and its name, in such a way that the path where the DDS file is is built and Orbiter searches for it, Orbiter finds it and we are all happy.
The problem is that as soon as I move the skin list file to the corresponding directory, instead of being in the root of Orbiter, and update the code, Orbiter no longer manages to change the skins and I suspect that it is not actually being able to build the path.
This is my function, and part of the header, any help is appreciated.
And that's how it was before the change, when Orbiter was still looking for the skin list file in the Orbiter root. And it worked.
