TrainSpecEnvMask material uv arguments

[disconnect]

Hi!

I can't find a tutorial about TrainSpecEnvMask material in RW. I know onlí that it uses an RGB image for texture +alpha for shinyness but other than that, nothing. What are the UV arguments controlling?

First UV argument is possibly Phong ( reflection tightness ), other than that I'm not aware of them doing anything.

Thanks, it seems that is the only one option for that material. I've decompressed some RSC rolling stock geopcdx files, and only that first argument is used, others are always 0.
