• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

"Abusing" extrusions

Has anybody experimented with "abusing" FSX extrusions to generate for instance overhead wires for railways? Could it work in theory? Or would it be impossible to get proper looking overhead wires using extrusions? To be true to prototype, both the zigzagging from side to side between poles, and the catenary "wavy" form of the upper wire and the constant height of the actual overhead wire should be modelled...

Or is it best to just simply place each pole and overhead wire section between a pair of poles as separate objects... and place them appropriately (programmatically, obviously). Modelling the overhead section as a single rectangle with a texture where only the actual wires have non-zero alpha should work, yes?

IMHO having overhead wiring visible would greatly enhance how truthful railways look in the sim... but then I am a railway enthusiast even more than I am a flightsim enthusiast;)

This thread: http://forums.flightsim.com/ts/dcboard.php?az=show_topic&forum=33&topic_id=301&mesg_id=301&page= has pictures of some truly amazing looking catenary... from train simulator addon packages.
