Problem using Blender Bridge

Hi, I’m using the Blender Bridge addon, to import characters and envelopment from Daz to Blender. I got great results rendering on Eevee, but I need to use Cycles. Now I have this problem on the materials, and don’t know how to solve it. Thanks for help me. The scene has a Sun light set on .5 strength.

Is that directly after the import…as the Daz > Blender Bridge will import the Vray materials and automatically switch to Cycles. It also imports the Daz sun etc…
So can’t really tell from this image what is happening.
