the 'night light' version of the guages will be the tga's with a '....._night' ending eg 2petitsb_night (and 2petitsb_d1_night for the damaged gauge :wink: ) usually these are greyscale and require no alpha channel with colour adjustment done using the relevant .mat file (ie same name as tga) try playing with the numbers in the 'colorscale' line (red, green. blue, transparency)

of course you could do it differently....
just remember to backup regularly and learn from 'mistakes'

good luck and have fun
