No it does not,
If you look at the ETO_GRVI_PPK the LeighLight on this aircraft work well with Ankors shaders on and of.
The ETO_GRVI_PPK model has a problem with the alpha layer because when you turn the shaders on the skin become gray, no colors. Can you post a corrected skin for this ?
I suspect the trigger for the LeightLight was never assigned in the ETO_GrV_GXB aircraft.
