Why is a model black in rendered mode?
I really really wonder!
Please help me!..
PS. I uploaded my model.3dm file, and please open the file.

It looks like your materials are applied to layers. But your meshes are set to use materials by object. You need to select your meshes, go to the properties panel and under the material button change “by object” to “by layer”.
