Map View distorted/fragmented (omnet++)

Hello,
I'm having the problem of distorted or fragmented maps using osgEarth in OMNeT++. The point of failure is not clear to me. As I am new to both, I hope one of you guys can tell me what's going on here or how I can narrow down the problem... Thanks!

OMNeT 5.0b3, osgEarth Library 2.5.0, Windows 7x64

That looks like corrupted texture coordinates. Which GPU are you using? Is the driver up to date? I also recall seeing this kind of thing with some of NVIDIA's features enabled...but that was a long time ago.

You may also want to consider moving up to osgEarth 2.7 (or better yet, the master branch).

AMD Radeon R7 200, just updated to newest driver, no special features enabled.

I'll try with the master branch, be back soon. Thanks!

Addition: the following error sounds like it may have something to do with it...


/d/omnetpp-5.0b3/tools/win32/mingw32/bin/osgearth_viewer boston_buildings.earth
[osgEarth]* FAIL, unable to load ScriptEngine driver for "javascript"
ERROR 6: Unable to load PROJ.4 library (libproj-0.dll), creation of
OGRCoordinateTransformation failed.
[osgEarth]* [SpatialReference] SRS xform not possible

    To   => WGS 84

It's possible. PROJ4 is typically built as part of GDAL but it appears you don't have it (or don't have it in your path).

Bringing libproj-0.dll into PATH did remove the error but didn't change anything. Waiting on feedback from omnet++

Sadly, upgrading osgEarth in my environment doesn't seem to be possible right now... https://dev.omnetpp.org/bugs/view.php?id=952
I'll have to switch to another PC, which doesn't show the symptoms.
Thanks for the help!
