Material from game not showing up in game

[TheVoid34]

In the two screenshots below, you can see that I'm using a material from the HU_floors package on that archway. Nothing particularly fancy. But when I cook the level and play it in the game, it has the default material, that grey and white checkerboard. It looks fine in the Play In Editor, but fails when cooked? Help? There are two parts in the level that use this material and they both come up as blank in the game.

Some times the last thing you added will not show, add it one more tine build all &, save out.

I bet it will show then

Also you are adding the fallback version of that material, which only shows by default on lower end machines. You should be adding the non-fallback version - ie that to the left of it.
