Unsolved Material Problem

So................I made new bed for Tseries and make it colorable
But when I set a chrominess to "matt" ,a bed is chrome

When I set to "Chrome" ,a bed is matt

Someone pls help :0 FASTTT

 

Hmm, odd bug. Does it still happen if you set it a little less than full matt?

 

yes

um.......
Can u check this jbeam for me?
I don't know why tailgate slot doesn't appear in game

 

I don't see how the jbeam would do it... checked it and seems fine. I think it is something in the model... I am not good at blender, so can't help there.

oops... I misread the thing, I'll check the jbeam again...

Nope, I don't see why something's going wrong....

 

I couldn't find the answer, but I rearranged the code to make it easier for other people to read and troubleshoot it.
Like KJP12 said, I think it might be a problem with the model. (maybe the material slot?) Are there any errors within the console when you spawn the vehicle?
