• 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.

Creating ripples on a fountain

I am trying to create a ripple effect on water such that circles grow outwards from a point. However, they always seem to grow in the vertical plane rather than the horizontal even though I am using only the X Scale and Z Scale together with X/Z Scale rates and goals. It doesn't seem to matter what I put in the Face statement either.

I am using the 4th right 3rd from the bottom image in fx_1.bmp as this seems to be appropriate, all I want to do is put this on a horizontal surface and make it grow to about a 3 metre radius.

Any advice would be gratefully received.

Maybe the rotor downwash effect of the helicopters can help you? That is probably the kind of effect you are looking for. Maybe you can learn from the code how it is done there (I am not an export in writing my own effects at all :)).
I made a similar effect using a piece of the Bellagio fountain code (fx_BelgFount1, fx_BelgFount2 in the effects folder) although I don't have it anymore. This is a fountain effect in the default Las Vegas scenery.

Perhaps you could use that as a starting point.

Thanks guys,

The missing piece was an undocumented statement "Ground Normal=1". This is not mentioned in either the FS2002 nor FS2004 Effects SDK.

It's workiing now.
