• 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.

Want autogen, but have no images

Since we are not blessed with overhead images of our country, we are having issue with Autogen.

I have a small bitmap, placed with FSSC, and now I would like to overlay that with some autogen buildings. Is this possible?
 
Autogen only works on photoreal images or on VTP polygons using the default textures. So I think when you place the polygon with FSSC it is very hard to get autogen on it.
 
Well... that sucks... and seems to be the case :-)

Let me see if I can overlay a map :D
 
Hi Nick.

The first problem is that your poly will probably suppress the default autogen. This may be overcome with the use of a "Dummy" rotated call. Check out AVSIM posts on Dummy calls, or Dummy RotatedCall.

Then, if the default autogen will show through the poly, you can place a VTP poly over the area, using SBuilder or Ground2K4, using a landclass number of 252 or 253... that is for photoreal poly placement.

The trick here, is that there are no landclass Custom texture tiles... only the autogen and they are in the "C:\Program Files\Microsoft Games\Flight Simulator 9\Scenery\World\texture" folder ( properly named, of course ).

When the BGL tries to display the Custom tiles for the poly, it will only find the autogen, and place them. Note: the VTP layer must be high enough so they are on top of all other VTP polys for that tile... Layer #63 should do the trick. The top-most layer's autogen will always show.

The shape of the poly doesn't need to be square LOD13 tiles... it can be any shape, and the sim will place the autogen tiles to fit the poly. Holger Sandmann found that "textureless" autogen trick.

You may need to place the VTP bgl into a project folder that has no "texture" subfolder... not sure of this, but it would be consistant with what is generally needed... otherwise there may be a memory leak.

Dick, as usual, thank you very much. I will now digest all of this :-)
