Can someone explain this to me?

This is the same model in game, yet in the world it shows the orange no texture even after a reload. Is it just a cache issue? Doing a custom world and would love not to have to clear the cache after editing materials it displays correctly in the inspector and asset browser.
Is there a reload asset key press I'm missing? Like control +r ?

 

Read the BeamNG log. Normally it gives you a hint why there are no materials.

 

Thats the weird thing it wasn't reporting what was wrong with it but i found out a color was selected to overlay the material like a "tint" i just selected black and it went back to normal. Not sure why this one file decided to do that but meh.
