• 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.

Need an Annotator like tool for large area building generation

I would like to be able to add Autogen buildings to photoreal area BGLs, where I don't have any vector data, that would work somewhat like the Annotator Polygon Region option for vegetation. I would simply pick a GUID for the type of house and then draw a large rectangular area and get many houses (perhaps a variety of sizes and heights set by a Properties Dialogue Box) with that angular orientation. Most downtown neighborhoods have that appearance and trying to populate a city quickly now - one building at a time - takes a very long time. Maybe a tool like this that generates the vector data for ScenProc with an underlay of a registered Google map. Any ideas?
Actually, instead of Autogen buildings, I have seen several third party sceneries - for example, Paulo Ricardo's Rio de Janiero and FlyTampa's (old) Hong Kong airport area - have a tremendous number of well textured buildings that seem to perform better (I think) in terms of FPS than do Autogen buildings of the same density.
 
Hi,

You could try to use the feature detection function of scenproc on a map that shows the buildings. I have heard other people play with that idea, but I haven't tested it myself yet. Once you have the vector data its relatively easy to turn it into autogen.
 
Arno,
Thanks much for your response! I will try that with ScenProc. Do I need a GeoTiff map photo? I haven't tried ScenProc except with OpenStreetMap data as a quick experiment. Currently, I just use FSEarthTiles to do an airport area in photoreal and then populate it with Instant Scenery instead of using Autogen Annotator but I would like to do more quantity of buildings and trees with Annotator.

Thanks again!

Dave
 
Hi Dave,

For now you would need a geotiff indeed. But I'm experimenting with other sources as well.
