I've always wanted to change the model viewer background
I know some people have already discovered how the the *.mod files work, and how their data is stored.
It would not be hard to do something like that, to add some backgrounds.
When i think on a model viewer, i have this idea of putting every ship side by side, or just the ones we wish, just to set their scale properly, and maybe edit the model.siz file in a better way.
But this is just me thinking out loud.
