Hi Ayman, We'll we've identified the issue. If OpenSim was opened on a computer connected to our university's (ethernet) network, we had the visualizer issue. If the computer was not connected to the ethernet, then it loaded fine. Also if it was loaded without being connected to ethernet, and then w...

Hi Ayman, Great, thank you so much for the workaround, that should give us a good working position until we figure out the rest. This is the bug tracker link, correct?: https://simtk.org/tracker/?atid=322&group_id=91&func=browse Over the next week as we install it on a bunch of computers, Ill keep t...

Hello, I'm hoping I can get some advice on a persistent OpenSim visualizer issue. The issue is that, once a model is loaded, it never appears in the visualizer. The model will be open and active in the Navigator, but the visualizer just 'zooms in' to the floor, and no model ever appears in the visua...

Hello All, I'm having a strange issue trying to manipulate a model. I'm working with the Lai et al., 2017 full body human model (https://simtk.org/projects/model-high-flex). The issue I'm running into, is that whenever I try to change something in the model and save it, the save never applies. For i...

Hi Ayman, Thanks for the reply. I've now tried reinstalling on a new laptop (Dell XPS 15) which is fresh out of the box, which shouldn't have any permissions issues (Im the only user account). I installed the program (by right-clicking and running as administrator) to C:\OpenSim 4.0. On running the ...

Hi Ayman, Yeah its a bit bizarre. After I fixed the geometry issue, it worked just fine, but then after closing the application for the first time, it started doing this. I've installed it on a few other Windows 10 computers and I'm having the same issue on all of them. One of my students loaded it ...

For fear of sounding like I'm battling a ghost in the machine problem, I can no longer get models to open. I changed the Geometry path to the correct folder, and was able to work on openSIM before after changing it. But after closing and reopening the software, I can no longer see any models when lo...

Hi Ayman,

Bingo, that fixed it, the path was set elsewhere. Thanks for the quick response!

Hello All, I'm just starting to get my feet wet with openSIM and downloaded openSIM 4.0. Regardless of which model I try to load, nothing ever displays in the visualizer, and instead the camera seems to default to a close up of the floor. No amount of camera spinning/moving/panning helps, it looks l...
