These are amazing! I've been doing reskins for YEARS and your work still trumps mine! You should ask JR if you can release these, because I would download them in a heartbeat!
I have been wondering also about there reskin policy on the f units, I have seen some on other websites, but cant find out if you/me/etc can upload them.
JR says contact them to host it on their site. I am currently waiting for a reply from them. Maybe the buffer can end up there to it would go well with the tank cars they have.
Hey ourense, I sent you a pm about a logo for a fictional railroad. I also included the colors that will needed to be used but if you can, please make a black outline and send me it so I can fill it on my own.
First off, you might want to try lowering the saturation on certain reskins, most notably the BN and B&O variants. The way they are now, they look too shiny and unrealistic. All the others look really good though.
Second, about the UB hopper: did you rotate the base texture at all? It looks like you may have flipped it 180 degrees on accident.
