(It's my first time using WED).
I am adding gate and runway markings (to the excellent EGCC Manchester v4 that has working autogate and safedock created pre WED1.6 ). I have managed to get the taxiways done for airplanes and vehicles and all the road markings done. ATC works as do the service vehicles so I am nearly there but for having trouble getting markings to stay on top of the concrete and even when I do (which seems to be very hit and miss) they don't show up in Xplane11 itself. (They will stay on top of the grass and then show in XP11 but not on taxiways).
I can create the necessary markings e.g. white text on red 23L- 05R or Gate numbers as gifs, tiffs or jpgs using Adobe photoshop but have no luck or consistency getting them into the scenery. I have tried importing jpgs as orthophotos but this doesn't work. Suggestions please- what programs to use, how to get them in and on top of the taxiways and then show up in XP11.
