not intended this way I guess ...
I quickly settled on this for the Red skin :
[Material_CarPaint_Chameleon]
ChameleonColorA = #A35420, 0.3
ChameleonColorB = #938824, 0
ChameleonExponent = 2.00
ChameleonCenter = 0
FlakesK = 0.3
ClearCoatThickness = 0.4
FresnelC = 0.12
SpecularMult = 0.25
AmbientSpecular = 0.7
BrightnessAdjustment = 0.8
AmbientSpecularEXP = 0.9
SpecularBase = 0.8, 20
FresnelMax = 0.4
then I get :
