Black Checkerboard Grid over material after building Lighting

Sorry if this is a simple setting, but I come from an Architectural visualization background and I am new to this.
This is a Revit model brought in as a static mesh

How do I get rid of the checkerboard grid on all of the materials?

Hi Rock5Studios,

How are you UV’s setup and the material for this mesh?

This appears to be more regarding the UVs though.

Can you post an image of your UVs for this?

If you’re not sure how you can do the following:

  1. Open the model in the Mesh Viewer
  2. In the top tool bar select and highlight the UV tab
  3. This should now display your UVs inlayed in the viewport like my image below.

If you have any further questions feel free to ask! :slight_smile:

Thank you!

Background…
Revit can export an FBX, but UE4 kept crashing when I tried to import it. I opened another renderings software I had (Artlantis) and saved it as an obj and brought it in.
