Materials change to all one material

Not sure what happened, but I opened up my sketchup project and most of my paint bucket materials all changed to one material. Also, any time I download a component it comes in as the wrong material. ie: the fridge is all tile. How can I fix this.

I’ve seen this happen when going from a computer with V-Ray installed to another that doesn’t have V-Ray, this has also appeared when going between versions where the license for V-Ray wasn’t applicable in the new version.

Do you have any plugins installed, most specifically Rendering packages? If so, you might look into their settings to confirm if they’re modifying materials for functionality in their plugin.

I have a vray plug in but it hasn’t been plugged in every time I use sketchup. what sort of things am i looking for in the settings?
