Render Appearance Images all disappeared suddenly

Anonymous · ‎04-23-2018

I'm new to rendering in rhino and I'm trying to render my model. I was familiarizing myself with the setup when I started experiencing issues. The first rendering I did worked just fine. All the materials and colors showed up and I didn't receive any errors or warnings. Then I tried rendering a different view and I got the error message "the following render appearance images are missing:" (every single material that has a render appearance image is then listed) I closed and reopened Revit but that didn't do anything. Then I opened the material settings and found that all of the render appearance images actually are missing throughout the whole material library. I could still view and select materials, but all of their images were suddenly gone. I uninstalled and reinstalled the material library, repaired my install of Revit, and still had the exact same error message and the materials editor was acting the exact same way. What else can I do to solve this problem?render settings I usedwarningview before renderingview after rendering
