the reason for this in general is the accuracy of the raytracing, controlled by the rayepsilon parameter (in every kernel's settings). if it is to high, it may show visible cracks where an invisible object breaks through a visible object; might i.e. also happen with a haircap object with an opacity map applied, when the invisible parts penetrates parts of the forehead.
lowering rayepsilon will make those cracks go away at some point.
please note that the daz slider text boxes only show 4 digits after the dot, but this parameter goes as low as 0.0000001 - so it might need a little bit of trial and error; it is also important to known, that very low values will cause texturing artifacts if the camera is far away from objects - so it might need some adjustment depending on the actual scene & viewpoint...
hi UruMike, t_3,
thanks for your tips
my rayepsilon is 0.0000 by default, so I changed it to 0.0001 and changed back to 0.0000, this annoying line was gone.

afaik the default is 0.00001 - what can't be shown in the daz slider value edit boxes - i'll replace that slider by a bigger text box, so you will see the full range when entering values. imo this value is anyway best edited by typing it in instead moving a slider...
ps: if you enter 0, it'll result in the minimum value 0.0000001 - which might cause texturing artifacts if you move the camera away; try something like 0.000005 - 0.000001 just as low until the crack disappears (the box takes those values, even if you don't see them)...
