The DAZ Importer fully supports three shaders: Iray Uber, 4-Layer Uber PBR MDL, and PBRSkin. Other shaders are only partially supported or not at all. Sometimes the result with an unsupported shader can be improved by applying the Iray Uber shader in DAZ Studio, but there are no guarantees. Normally we have to tweak the nodes in Blender to obtain the effect we want. However, to do so we often need textures that only affect the unsupported channels. In the last version of the DAZ Importer we can import such textures, even if they are not used by any nodes in Blender.
Material Editor so we can edit all skin materials at once.The simplest way is to turn down the value of the base color of the principled node.
The other materials still contain unused textures and node groups. To remove them and keep the node trees tidy we can use Advanced Setup > Materials > Prune Node Trees with Keep Unused Textures disabled.
