Technical Issues Corrected in STK 12.0.1

Issue Id Release Note Category
109974 When loading large 3D Tilesets, the entire 3D Tileset json tree was retrieved. This resulted in a proportionally large memory footprint and increased load time.  This has been corrected to load nested tileset json definitions on demand, vastly improving 3D Tileset load time and memory footprint. 3D Graphics
110614 An issue was introduced into the MDE tool in STK 12, where loading a COLLADA model would terminate the tool.  This is corrected. 3D Graphics
110781 Resolved issues with Virtual Reality devices that caused slow scene animation and application freezes. 3D Graphics
110794 Communications/Radar contour lines could cause STK to exit if the contours generated only contained one point.  This is corrected. 3D Graphics
110805 Corrected issue with two-sided lighting on MDL models. 3D Graphics
110852 Large 3D Tilesets that cover more than half of the globe, such as the Cesium OSM Buildings tileset, would not pass visibility tests in STK. This is corrected. 3D Graphics
111202 Certain glTF models entered a state where the loading of the textures would not get detected as complete. This resulted in indefinite redrawing of the 3D Graphics window as long as the model was in view. This is corrected. 3D Graphics
110420 The default A vector for the DotProduct calculation Scalar for GroundVehicles and Ships has been updated to be the Position vector. Analysis Workbench
110698 The epoch control for the Solar Array Power power source no longer causes STK to exit. Astrogator
110709 Attempting to use a gravity field for third-body propagator functions while propagating the state transition matrix no longer causes STK to exit. Astrogator
110714 An issue where Astrogator Scripting Tool sequences would fail upon attempting to update internal data due to international locale settings is corrected. Astrogator
110292 Unloading a scenario that contains an Aviator aircraft that uses AWB components and another object with a sensor while EOIR is installed could cause STK to exit. This is corrected. Aviator
110850 Extreme attitude changes could be encountered when certain settings are used when transitioning to racetrack procedures. This is corrected. Aviator
110899 The Elevation Azimuth Cut Antenna pattern had the data axes reversed.  This is corrected. Communications
110625 The directory selector of the EOIR details dialog now correctly allows the output directory to be changed. EOIR
110626 Facility size parameters were not being saved correctly in STK 12.0. This is corrected. EOIR
110713 Loading scenarios with facilities saved from STK 12.0 would sometimes cause STK to exit when the  synthetic scene was rendered. This is corrected. EOIR
110872 The EOIR properties (Processing Level, Scan Mode, Smear Rate, Motion Blur, and Jitter) are now correctly positioned below the Spatial, Spectral, Optical, Radiometric tab group. This issue was found on Japanese and Korean versions of Windows, but may occur on other variants. EOIR
110901 The issue where STK could exit if an EOIR sensor is deleted and the EOIR Scene's details dialog is displayed and used is corrected. EOIR
111110 An issue where Sensor Connect commands would not function properly when EOIR was installed is corrected. EOIR
111114 Corrected an issue where the sensor field-of-view was not updated graphically in the 3D Graphics window when settings for Number of Pixels and Detector Pitch were changed. EOIR
110475 The position interpolator has been corrected to lessen the impact of numerical noise when using an interpolation order of zero. General
110556 The Navigation Files UI plugin now properly handles "predicted" satellite outages with no end date/time specified (NANU type FCSTUUFN). General
110619 The STK CZML Exporter now works properly from STK Engine Applications. Plugins
110607 The SEDS login dialog could sometimes be displayed when:
  • accessing the AGI terrain server
  • validating connections to the AGI SEDS server
This happened when the guest account should be used. This is corrected.

110873 Propagation of GPS satellites could fail in STK 11 and STK 12 if the source of the GPS almanacs was set to AGI server (default) and the date of the propagation was set between May 15th, 2020 and July 6th, 2020. The source almanacs residing on AGI's ftp site have been updated. This is no longer an issue for STK 11 and STK 12. User Interface
