WHAAAAAAT?! :eek
Wow, that's awesome! Where did you hear that? When I first spotted it, I immediately thought of him, and went through his progress thread over on SciFi-Meshes, but I only found rumour and speculation, no confirmation from the man himself.
Also, the deflector on his model is a slightly different shape, it seems to me.
I'm obviously not going to point to colouring or materials, but the mesh proportions and certain shapes seem off. Also, Richter has erroneously left the Generations aft-nacelle tags on for his TNG version - not that they'd be difficult to remove.
You could still very well be right, though - the deflector's apparent shape changes a lot with the viewing angle, for example. It's a testament to CBS and Richter's abilities that we seasoned starship eyeballers are having such difficulty distinguishing, not only which CG model is which, but where a CG replacement has occurred in TNG-HD and where it has not!
