So I've been playing with the old ETK-I and ETK-W wagon mods (using an older version of the ETK-I, which can be found here) and I just can't stop being bothered by this one detail that's off: So what I'd really like to do is basically make modified ETK-I front doors, where the only difference is the lack of chrome windowsill trim. It seems like it should be simple, just changing one little material on each door and then doing some part renaming, but I haven't a clue how to do this exactly. Can someone please help me out? I'm not afraid of getting my hands dirty (assuming I really have to delve into depths like using Blender, which I took a look at and yet still have no idea how to use at all). Thank you all in advance to whoever replies!
