• 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 How do I place polys in FSX?

Been trying to match my ground poly to the photoscenery but in vain.
I have filled the Atlantic ocean with ground polys!

I know you have to enter coordinates for your ground poly in MCX, but how do you guys achieve to match your polys to the photoscenery exactly?

Is it an infinite trial and error thing?

Thanks! :)

The screenshot shows the closest I've got so far

Hi,

No, it is not trial and error at all. But you need to start with the right reference image in your modelling tool. You can't just take any image, you need to make sure that it is in the flat earth coordinates that FS2004 uses for ground polygons. The MCX wizard will then convert to the curved earth of FSX for you.
 
Thanks Arno!

What do you mean by right reference image? I usually take a snapshot of Google Earth, put it as a background (hence my other thread) and start working based on it.

Hi Peter,

Well Google Earth could be a reference image indeed. But to get the position right in FSX you need to know the exact coordinates of the 4 corners of your image. Then you can align it.
 
Still I can not get this to work man.......:(

I find my poly anywhere but where it should be.

I found my runway a few miles away from my airport, I found it sailing on the sea, I even found it on a mountain after searching for it for a while but NOT on the airport!!

Is there a good tutorial for this?

Thanks!
 
Are you using the period as your decimal separator in Windows, and not the comma?
 
I think of one quick thing.
You can set the material that you use for satellite photo to be more transarent. Move the whole thing try to locate something that look remakable such as corner of the building to 0,0 point in Gmax.

Then you go to FSX or FS9 and slew to that point and get coordinate.
Now it should fit in.

By the way, if you use ground poly and tweak the code manually. It never matchs photoscenery since the curvature of the earth in FSX.
You need MCX and use ground poly wizard to do that.
 
Hi,

If they are miles of, I think you might have made a mistake in entering the coordinates. MCX takes them in decimal form, while FS often displays them in DD:MM.ssss. Are you sure you converted that correctly?
