Need help changing materials on a file made in a different software

I opened a file in Rhino which was created in Archicad, then saved as a Rhino file. Many of the objects were block instances, but I was able to explode them into layers. I can change the color of the objects in shaded mode, but when I change the material in rendered mode, it does not show up. How do I fix this?

Hi Elena -

It’d be better if you could attach a small sample file with your question so that we don’t have to guess where you are getting stuck. When you change the color of the layer, you will see that change in shaded mode. To see things happening in rendered mode, you will need to apply a material to either a layer or an object. If that’s what you are doing, and in addition to providing a small file, please run the Rhino SystemInfo command and copy-paste the result here.

The file came with materials already applied from Archicad, and when I try to change the material to one from the material library, it does not change/show up different in rendered. I’ve included a sample file with an object from the file I’m using. In this file, even though I’ve applied a lavender paint material to the object, in rendered it still shows up as green (like it was when I first opened it).

Hi Elena -

You have applied the lavender material to the layer that the object is on, but that gets overridden by the material that is applied to the object itself.

From the object’s material drop-down, you can select Use Layer Material to remove this override:
