Hi Dick;
On the GN Freight packs a couple of mapping issues have surfaced in using the FT locomotives. On the FT A unit the headlight texture is missing (See picture). The B unit if you get to close the roof detail disappears. If you pull back it reappears so I am thinking this as to do with LOD setting?
Also, after the upgrade all the GN locomotives seems to be darken to much compared to GN rolling stock.
Let me know.....regards, Gerry
