A quick update and a thank you to all the folks that have helped me with the editor and models today. I have crawled my way through the first ship silhouette and got Blender more or less set up the way I need it. Hopefully the next ones will go a bit faster now I am not fighting the tools all the time!
Here is what I have come up with for the Shinshu Maru Troop ship...
I have worked out that the angled view is 045 degrees, that all three views are Orthogonal and that the scale is correct when compared to several other vanilla silhouettes.
The brightness seems about right but may want darkening a little. I would appreciate feedback.
The only issue I still have is knowing where to put the red stadometer guide marks since I don't know the convention there.
