• 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.

Proximity of Autogen Objects to Scenery

Hi,

Autogen objects keep their distance to my custom built scenery, at least to some. With others Autogen object some extremely close.

Is there a way to influence where and how far away Autogen FS9 objects (eg trees) appear from new custom scenery?

Do you mean your custom objects (made in GMax or FSDS) or scenery such as an airport?
 
Hi,

It is mainly determined by the size of the bounding box of your object. So if you have designed them all center nicely around the 0,0 origin, then the autogen should appear quite close.
 
If oyu do not have any exclusion rectangles then you might want to add them to remove objects that are too close.

Yes, depends a bit on the tool you are using. But for example in my MDL Tweaker tool you can view/change them for Fs2004 MDL files.

But be carefull, as a wrong bounding box can result in disapearing objects.
 
I don't know if you can control it in FSDS, you don't have a fine control over it in GMax either as MakeMDL determines it in the end. That is why you probably have to tweak the MDL a bit in the end.
 
It appears that bounding boxes are always aligned rectangles going from north to south, i.e. if your mdl is aligned 45 degrees, you can't just do the bounding box aligned 45 degrees, instead it is aligned north to south:
+ = Bounding Box
\ = Object

So in order to get autogen closer to my object (which is a diagonal fence in this case), I would need to break it down into smaller pieces.

Did I get this right?

Yes, that is correct. The bounding box is made up out of small boxes. If one box is too big, you can split it into 8 pieces and define for each piece if it is a crash zone or not, but in the end you always define the crash zone is cubes.

So the easier solution might be to rotate your object 45 degrees in the design tool and do the rotation when you actually place it in the scenery. In that case the crash box will rotate nicely with it.
