Further clarification: First and foremost there was nothing wrong, for what I make, using bge, which is ship routes based on the UK coastline using srtm2 data.
Ships and sailing vessels could be easily made and endless scenarios are possible. They just needed the imagination of the route creator (myself)
Al routes were simply made and kept to under 5 meg using alt and d etc.
Blender and its embedded game engine works fine. However the powers that be changed the format.
Again obviously Blender Artists has no further place for real life simulations going by the response, feedback, discussion, for real life simulations . They seem to have pushed this category over the edge.
I know all about upbge and used it as a trial early on!
If you want bells and whistles, sky dome etc, and endless other thing could easily be included using bge, but in my case, not used, as kept all routes under 5 meg.
I think the various happenings also completed the picture
This post is mainly a general letter outlining what I make. It is not a personal letter, as some information in the personal letters are very useful.
Cured most of the mass of adverts
from various sources. Regarding the ships I might continue, as what I make is part of history. Regarding malware, far as I know, no sign of it in the routes, however always best to check for malware.
