I was looking at replacing some of the ship equipment with custom designs. There are a number that use the same model and I'd like to have them easier to identify on sight plus making them a bit more interesting in appearance. However, I can't get the game to recognise new designs in <artdefine>. In the designer the thumbnail is blank and no part is displayed when I select it. So I'm wondering if others have got it to work and if I'm just missing something or if it is hardcoded somewhere and can't be changed in the way I want it?
