Since you're a team member I must believe you and admit defeat to this. I apologize to the dev team.
Well, if I'm wrong, then who ever made your Scimitar Model/Texture must have used the same references as STO, because the textures are nearly 1:1 with each other. Place meant of all the little details, the little squares and rectangles details, are exact.
Credit to both texture artists I guess. The detail common to both models are not on the Scimitar in Nemesis.
Is it possible your texture artist used the STO model as a basis for his texture? Not ripping it but inspired by? I just can't get over the similarities.
