Hello,
I tried the setup, including disabling all three dynamic lighting options in FSDG configurator. After replacing the dds files, adding the bgl file, setting max light points to 1000, opening P3Dv5 and moving all slider full right I do not get any dynamic lighting on FACT. Default Piper Cub, PMDG 747, Leonardo MD80 and default F-22 Raptor are fully unlit. To make sure, I moved to YSSY to see if that DL install is still OK and all is well there.
