Interface changes with stock model files When I open a a Stock 3D model I downloaded, the entire interface changes. I see a "Default" layout option, but I don't see the stand "Layout" option at top of page. Is it possible that the model I have was created pre 2.8 &amp; needs to be converted?

The model also does not have a Camera, &amp; I can't see to find the "Add Camera" option that I see in basic tutorials.

I have attached screenshot of the UI as it appears with my stock model. Total Noob thanks you
You can bypass the user interface saved on the file and use your default one.

Open blender.

Then use File>Open to select the file you want, click on the gear on the right side and uncheck the LoadUI box.
