Hello, I would like to create a sound and repaint mod for the BR 411 in TSW. This mod should be selectable as a standalone variant and include a repaint into the BR 605 as well as a sound mod. However, I want it to be selectable and not overwrite the entire sound of the BR 411. What is the best way to achieve this? Sorry for my Bad Englisch the text ist translated with Chatgpt because i'm an idiot in Englisch
