Hey.
This is the only report I've gotten so far, so I believe this is caused by some addon shaders.
It is quite a process to alter the whiteness of the snow, since the textures are split into many parts.
But if you wanna try, you can alter the brightness of the snow of the files "apron_1_hw.dds" "apron_2_hw.dds" etc.
I spent quite a long time refining these to make the match 100%
