trying to do texters on a engine

i need help i made a modified version of the d-series v8 in blender and when i try it its missing textures in game can someone tell me how to fix the texture or something?

 

in the menu on the bottom right in blender, one of the tabs there is pink circle with a checker pattern on it called "material properties".
if you go into that tab, in the box at the top, it will probably say pickup_engine.001, where it says "material.001" in the image below. you want to open the drop down menu i've circled, and click "pickup_engine". once you do that, it should work.

 

thanks it works but with the modified part of the engine some have textures and some have missing textures

 

You would need to re-unwrap the engine model & add textures to the missing bits that weren't originally there

 

how do i do that?

 

im trying to do brakes and no matter what is still have no textures even when i have the right texture can someone explain?
