TU/Metallic not reflecting environment

[YuyouWu]

I'm on 1.9 and using the following config for some model

MATERIAL // Metal
	{
		shader = TU/Metallic
		
		excludeMesh = flagTransform
		excludeMesh = Flag

   	 	float = _Metal, 1
   	 	float = _Smoothness, 1
	}

When I'm in the Assembly Building, I can see the surrounding being reflected by the material:

But when I'm on the launchpad, surrounding is no longer being reflected:

Is this my configuration issue or is reflection outside of VAB not supported? I've also tried setting shader to SSTU/PBR/Metallic as well but getting the same result.

In game reflection was off.
