Blanking techniques

[UnionPacificFan1005]

I have a locomotive I'm trying to reskin, and the method where you paintbucket a layer underneath the bump map and then adjust the saturation and lightness isn't working for it. Does anyone have any other techniques for getting a blank?

FYI, I'm trying to reskin the JR Alco S4, specifically the one included in the Pennsylvania and Berwind content pack.

I went through it earlier, it doesn’t really go over blanking.

I tried doing one by setting alpha to grayscale with alpha transformed, I ended up kinda making onve, but I lost about 30-50% of the detail.
