The TerreSculptor heightmap editor pre-beta build for 2011-06-24 is available for download from the HMES Beta web page. See the Build Notes page on the wiki for a complete list of the build changes.
This is an interim build that fixes two crash bugs.
1. Startup logged crash "System.FormatException" in mscorlib.dll Convert.ToSingle(string). The crash was traced to a broken function in the Microsoft Windows .NET dll file on some international versions of Windows. The fix was to re-write the TerreSculptor code to not use the broken Windows dll function.
2. Preview control stop crash on computers equipped with Nvidia video cards when using VBO render mode. The crash does not occur when using VA render mode or on ATI video cards. The crash was traced to poor/lazy Nvidia driver code that hangs instead of returning gracefully. The fix was to ensure that all VBO arrays were primed during control initialize long before any OpenGL VBO calls occur.
Thanks goes out to those individuals who helped in testing the fixes.
