You will see this on the P3Dv4 ORBX forum
Today all scenery is black and grey, no colour.
Here is Norway in summer
here is Cairns in spring
I restarted the scenery library, still black an grey
I restarted the computer and restarted P3Dv4.5 and still black and grey.
Any suggestions as to how to fix this.
The aircraft colours are fine and show in full colour.
