I'm putting a scenery location in at Circle City (PACR). If you look at the community there, there is no shoreline for miles.  So I used SBuilderX to put in a "line tool" shore line and it looks fine. EXCEPT I get black rectangles on the water that have a HARD surface. If I "slew" over it the plane's gear locks down.  Just wondering if anybody else has seen this and if there is a fix for it. 

Thanks

Problem Solved.

There appears to be an incompatibility between ORBX and Prepar3D when it comes to "frozen surfaces". You will notice, if you are using Vector and P3D, that many shorelines in the northern areas, especially around communities, have no shorelines. Vector leaves out the shorelines on purpose to avoid this problem (As with Circle City, AK). In the above screenshot, you can see, I added (manually) a shoreline where one was "missing." And the result was the black rectangles.

Solution #1: If you go into Vector Configuration under Water Features, you need to UNCHECK the Frozen Surfaces (in winter only) button.  Of course your lakes and rivers will not freeze in winter (showing ice), but the black rectangle problem is solved.

Solution #2: The other way to solve the problem (without un-freezing the water) is to look in a scenery folder for a bgl that creates the shoreline and change that bgl from "bgl" to "off".  

The incompatibility is not a major problem as long as people who are doing scenery design are aware of it. I hope this post helps those people and will save them the time I've lost trying to solve the problem.
