Issue with another bump map appearing on clothing in game

Re: Issue with another bump map appearing on clothing in gam
blue channel level can vary from 0 to 255 with each 16 steps belong to one palette sample. For example, setting blue value to 0 is a "lowest level of first sample", value of 15 is the "highest level of first sample", value of 16 is the "lowest value of the second sample" and so on. If I'm not mistaken, the "plain surface" (no details) is on first sample, so painting blue to 0 level will drop surface micro-detail effect.

If you paint spec to RGB (0, 0, 255), you get a paint blue color on it and blue channel value will be 255 (highest 15th level of 16th palette sample will be used in game). if you paint to (140, 20, 10) (dark red color), you specify 140 as specular level, 20 as reflectivity level and 10 as substance selector (level 10 of 15 for the first palette sample).
