Oh. I didn't think about that. I'll attach the files.. You can change the livery / design of them via Blender and UV mapping. Also, if you have Paint.net, it will be easier to change the UV maps. But there is an exception for one of the vehicles. E400 MMC. The E400 MMC does not have UV Mapping. It is in `Stagecoach Beachball and Local liveries` as well.
Sorry for the late reply, but the files can't be opened. I have tried the default Windows extractor and 7-ZIP and both return a 'invalid archive' message!
Oh. Do you know any other way we could do this? Do you have Roblox Studio so you can extract the meshes?
So, with these models, you can change the UV map via Blender and Paint.net. Plus, If you can, try make the doors work too with the original horn sound with engine. Here you are. I made them in `DAE` files as it was the only option you told. Hope these work, see you soon.
Note to anyone who installs: Please tell me if you receive both of the vehicles. You'll need to go to Blender and import them. Thanks!
Probably never, the modding community rarely ever do commisions for free. Also a model is totally different from an actual mod, and it's much more complicated alltogether than "importing a model into blender".
