Hello Ralf and thanks for the detailed information.
Glad you got the image showing on forum thread.
Regarding putting the collision spheres on, you proably know that they will not work in sailsimulator unless you "mend" them in wordpad.
But they will work OK in the motorboat simualtor.
At least that is the case on my computer. but easy to mend with one giant sphere around the small ones, copy the line with file opened in wordpad, delete giant sphere and paste in value.
As far as I know you still have to fix them as I don't think the "bug" has been repaired to make them work in sailsim. Just the small spheres seem to work fine in motorboat sim without the "repair".
I gave up myself fixing them as rarely use the sailsimulator now(although my routes are set in about 1800 but no option), and use the motorboat simulator, due to problems with sailsim locking up when I change settings.
So, with many of my later quays, etc the boat sails right through them in sailsim but works fine in the motorboat simulator. Collision spheres need to be in line with the ones on side of boat. I find on some of my "rocks" and ,searoad and wall, that boat can sail over or under them and object may need more than one row of collision spheres on them.
Be interested when tides come in the simulators, as would need to cover all of seawall for 9.3 metres at Liverpool down to about 7 metres around welsh coastline.
I don't know what the tides would be like regarding height for your area.
Always been puzzled, do we make a sceneries for low, medium of high tide? Not very realistic at present with no tides at all so I pretend its full tide height?
Regarding the append function I used that to make the different size masts and sails by keeping them seperate, fort he boats then scale them up a bit to a scaled up ship hull and adding them on as seperate units.
I have made a full town with about 300 houses in the Egypt scenery. Just rotated some house at right angles angle or joined them in groups, pairs, etc. Changing the colours and roofs, etc sounds a good idea of yours.
With my previous routes I worked over an actual map of the scenery whem making the dem. map, background button, so could place the items fairly accurately in scenery designer with creeks and rivers visible.
With using srtm data from now on, a bit more difficult as working over greyscale but you can make the water as pink dem to work on, as all water is zero height to start, so all the bays, and inlets can still be seen in scenery deisgner. for placing content.
But I have always got the excuse that rivers, and harbours were entirely different in 1800 from now.
