Changing Bell Textures

Is there a way I can change the bell textures of the NKP Berkshire from K&L? I've tried replacing the textures with different ones from different trains and it hasn't worked. Any advice?

Without looking at the asset its self since I don't own it, I'll say that probably not especially if they've used some of the modern texturing techniques with PBR.

If the bell is done in the older methods, it might be possible. Is the bell a separate add-on, or does it share the texture map with the rest of the loco? If it shares the UVW texture map, no matter what other bell texture you include, it won't see it. The only way to get around that is to edit the UVW texture map and replace the bell textures.

As I said, I'm just supposing here.
