could anyone help me with the illumination problem

I am making some hands for player models,everything else goes fine,only the illumination of these hands don’t look normal. The problem is when I go into a dark place like the dark room in the gm_construct,normally I shouldn’t be able to see my hands,but with these hands I made I could and the luminance is quite brightly,while in the bright place my hands sometimes look too dark.I have tried many combinations of illumposition but none of them fixed it.Could anyone told me how to do,thanks.

Fixed it by changing $sequence.
