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 |

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 |

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. |
User Interface |
| 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. |
