Well, I just found another topic here about the same problems : https://forum.corona-renderer.com/ Corona SSS and Daz3D People
Somebody seems to find a way to resolve the problem by changing UV Tiling mode to UDIM and interpolation to Bilinear Faster in the Picture Shader Tab. But a new problem has come : I cannot find UV Tiling option in the Shader Tab 
Has somebody know where is it ?
Thank you !
