"_LIT" textures

[WolfAir_737]

Hi,

There are some liveries (like default 172, 747, etc.) that seem to use _lit texture files. So here are my questions:
1. Are they actually using those files?

2. If so, is there any easy way to make custom livery "blend" into them?

So it's a WolfAir-themed C172 paint. I noticed there's a "_lit.dds" on both fuselage and wings textures. Other liveries have those included, but I don't know if they're making much difference.

Thanks in advance!

It should be using the LIT file by default, if not backup your .obj files and open the fuselage obj using notepad and add the line 

TEXTURE_LIT fuselage_LIT
