• 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.

P3D v4 How to Remove ORBX shoreline and land to match foto-ground image of SAWH

Hello forum, I think this might be the right place to get started on this with SBuilderX

I made the fotoground for SAWH with FSEarthTiles, and are pretty far along with the ADE file using ADEP. I'm at the point now where I need to remove the ORBX Vector and Landclass South America land that is peaking through in some areas of the fotoground as shown in the pics below. I've included a picture of the default SAWH with the ORBX Vector and Landclass SA, the Globabl airport SAWH from ORBX is already disabled.

I think SBuilder is the tool I want, s did various searches here in FSD and found a tutorial linked repeatedly that I downloaded from AVSIM called "terrain_design_for_flight_simulator_x". I installed SBuilderX315, then I drew an "Exclude all terrain items" vector poly (inner poly in the SBuilder pic), with a larger "Hydro Generic Ocean Perennial" vector poly around it (outer poly in the SBuilder pic). The results in the sim did not change anything. So I think maybe I'm missing something.

Any help would be appreciated.

Hi! That is an outstanding project you have!

I had to do the same thing in my project as well. I had to remove the post-eruption ORBX/Default scenery around Mount St. Helens. This was achieved with an exclude rectangle to remove all existing shorelines, road data, etc to achieve my end goal. You can do that via the Exclude tool in SBuilderX. It will bring up a tool that will allow you to draw a rectangle in the area in which to exclude your ORBX stuff.

For me, I chose the "All Objects" selection box in the list that appears since I was eliminating everything in a 230 square-mile area and starting from scratch. This included realigning the Spirit Lake contour to its pre-eruption data and reestablishing the pre-1980 Highway 504 alignment.

A word of warning... You will likely want to replicate your shoreline using a series of segmented lines around your project, then adjust the attributes of that line under the "Properties" dialog of that line. You'll need to do this because once you exclude the ORBX stuff, you'll lose the wave effect. Under the "Vector Lines" tab of the properties dialog, select "Shorelines Generic Ocean" or ""Ocean Bank Surf."

(for mine, I chose "Shorelines Generic Lake".)

Once you've done that, go into the "General" tab of that line's properties dialog and then experiment with the "Reverse" button a couple times to get the waves to show up on the right side.

It'll take a few test compiles and back-and-forth restarts of FSX to do this, but worth it in the end.


A Exclude Rectangle compiled by SDK BGLComp is able to eliminate Effects (including "waves"), but not CVX vector lines and/or land class polygons, etc..

http://www.prepar3d.com/SDK/Environment Kit/BGL Compiler SDK/Compiling BGL.html#ExclusionRectangle

To "remove all existing shorelines, road data, etc.", one must use a terrain polygon, which is a CVX vector object compiled by SDK SHP2VEC.

http://www.prepar3d.com/SDK/Environment Kit/Terrain SDK/Terrain and Scenery.html#The Shp2Vec Tool

http://www.prepar3d.com/SDK/Environment Kit/Terrain SDK/Terrain and Scenery.html#Vector Attributes


Alternatively one may 'cover up' default and/or 3rd party addon CVX vector lines and/or land class polygons, etc. with custom photo-real imagery land class.

Custom photo-real imagery land class using aerial / satellite imagery from ex: FSET ...is compiled by SDK Resample.

Hmph. Interesting...

IIRC when I was doing my initial design of the Mount St. Helens project I ended up having to use an exclude rectangle to remove everything, because the Highway 504 alignment by ORBX and the current Spirit Lake shoreline wouldn't go away unless I did. I had issues where the pre-eruption shoreline I'd done in SBuilder showed up as an inset contour of the pre-eruption lake profile, while the rest of the post-eruption lake still showed through.

May have to duplicate that again and temporarily remove my exclude.bgl file to test that out.
