GMAT build: August 18th, 2014
Step 1: Put the following .3ds spacecraft models in GMAT's ...data\vehicle\models : Mir.3ds, Astronaut.3ds, GlobalHawkObj.3ds, SOHO 02.3ds, HST.3ds. These models are attached.
Step 2: Start GMAT. Open Spacecraft resource, go to Visualization tab and Upload Mir.3ds. Change Scale to 5. Click OK. Now Run GMAT. You will see Mir.3ds in OrbitView window. Now close ALL graphics windows.
Step 3: Re-open DefaultSC again and go to Visualization tab. Now upload Astronaut.3ds, change the Scale to 25. Click OK and Run GMAT. You will see Astronaut1.3ds in OrbitView. Now close all graphics windows.
Step 4: Now re-open DefaultSC and upload GlobalHawkObj.eds model. Change Scale to 10. Click Ok and run GMAT. You'll see GloablHawk.3ds in Graphics window. Now close all graphics windows.
Step 5: Now re-open DefaultSC and go to Visualization tab. Try to upload default Aura.3ds. You will notice that Aura.3ds does not show up in Dispaly window and the FileName path also does not update.
This is the BUG.
Step 6: Notice that if you try to upload Mir, Astronaut or GlobalHawk (in any order), they upload just fine and if you run GMAT, then they show up in Graphics as well. But if you try to upload any model other than Mir, Astronaut, GlobalHawk, you cannot upload that model and the FileName path does not upload.
The common factor seems to be that the first 3 spacecraft models upload just fine and show up in Orbitview. When you try to upload any models other than the first 3, it is then when the models do not show up in Display window and FileName does not update.
Using Fresh GMAT, try to upload different set of models: HST.3ds, run GMAT, then upload Soho 02.3ds, run GMAT, upload Mir.3ds and run GMAT. These models will work just fine. Now try to upload any model OTHER than HST, SOHO 02 and Mir.
That fourth model will not upload and Filename path does not update.
