This is a model of a League Frigate from the Fading Suns [link]
universe. This model is based on concept art by John Bridges and Kathy Schad, which you can see here: [link]
Please note that I do not have any connection with the publishers of the Fading Suns game materials, and the underlying concepts of Fading Suns starships are not my intellectual property.
Please credit me and leave a comment here if you use this model - but also be aware that the context of the model is not a universe over which I have any authorship.
The preview picture is a "serving suggestion" only, although a greyscale map is provided in the zip file which should allow users to get the same base colors on the model - provided that one is willing to make the necessary tweaks for one's software.
The zip file contains the following, with the intention being that the model should be as modifiable as possible by end users:
Sketchup files for the main body and dorsal turret
STL files for the main body and dorsal turret
A Blender file containing the entire model
An OBJ file file containing the entire model (the dorsal turret should still be rotatable along the vertical axis)
A PNG file of the greyscale map used to "drive" the base colors
A VUE file of the model, textured and lit as seen in the preview
Hopefully, this model retains enough of the spirit from the concept art to be useful.
