Material mysteriously dissapears

[ezra 10]

Would anyone here have a clue as to why my material selection only displays on one of

four parts of a model?  This ramp has only 4 parts, tapered ribs(3), front plate, back plate, and top.

I added wood-grain material to each part and saved it, and yet when I opened the assembly the

change did not happen on three  of the parts. I never got the option to upgrade the assembly.

 

Thank you,

Most likely a graphics driver issue. Make sure you have the most recent certified graphics driver. This used to happen to me all the time as well. Switching your display style a few times may help with this too.
