• 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.

FSXA Sound effects, what means radius?

I tried to install the bellsound of a church as effect to a little village. It works but you can hear the bells 15 km distant.
I tried in the Cntrl-fx as Radius 5 then 3 then 1 but there was no change.
Thank you Gary, in the meantime I found your thread (but I didn't understand all of it) So I found the radius is not only in the Cntrl-fx.
The second link concerns P3D. Is it usable for FSX also? I have no P3D.
Hi again:

MS Game Studios' ACES as developers of FSX made a slightly modified version of FSX available under the name "ESP", that was briefly licensed by Flight1 before ESP was acquired in its entirety for "Academic" development and retail by Lockheed Martin as "Prepar3D" (aka "P3D").

ESP and 'most' scenery in all versions of P3D is still default "FSX", so nearly all versions of P3D SDK docs apply to FSX as well.

However, the original MS-FSX SDK docs are here:


The somewhat more easy-to-read Lockheed Martin P3D version 1.4x ESP / P3D SDK (FSX SDK equivalent) docs are here:


FYI: The downloaded installer includes both Lockheed Martin P3D version 1.4x (FSX) SDK and that SDK's documentation. ;)
