In solaris, when i use editmaterial to lodad one material from materiallinker, some nodes changed to GenericShader. if i edit some other shaders such as ArnoldShader, all nodes bacame GenericShader.
can it fully reconstruct the shadingnet?

If I remember correctly, there is no custom shader translator for Arnold, so the default is always just a generic one.
