now, adjusting UV tiling from materials or c4d tag material didn' t solved the problem time ago, i just reduced the glossy for a better tweaked result and for not having this cut, now i' m facing this problem in a bigger way, just....it' s different now because seems that the problem is the shadow that cast the area light, if i move down the area light i see this problem disappear...but it' s horrible that cut of the shadow i don' t know why the light give me this perfect cutted shadow, here the image:

any suggestion? I tryed to increase the samples of the area light without results
