[Bug] .X file lightning issues

[RakagoBVE]

In the Object Viewer, .X models display correctly and they are affected by night lightning. However in-game they are always lit, and they are not affected by any light source.

My game version is 1.11.1.1 64-bit.

This bug is still present in version 1.11.1.3.

Images here:

Although .x models are not affected by the .Brightness command, they are affected by the .AmbientLight command.

ObjectViewer is actually 'wrong' here, although I haven't got to the bottom of why exactly.

The DirectX format explicitly expects materials be be emissive. (fourth line of the material definition sets the emissive color, which is a required template)

[RakagoBVE]

It shouldn't light up as the emission color is set to 0,0,0. If it's set to 255,255,255 then it lights up in Object Viewer as well.
