Ovito crashes as soon as I open a Lammps file with it.
I tried the exe file and also the compressed installed version for Windows, and I still have this issue. Any suggestion?
This could be an OpenGL / 3D graphics driver problem. Could you please post the information shown by OVITO when you select “System Information” from the “Help” menu?

I looked in my notes. Over the last few years, there have been a few reports that AMD Radeon graphics chips from the 5000, 7000 and 8000 series have caused OVITO to crash on the Windows platform. The hardware or the graphics drivers do not seem to fully support the special OpenGL functions that OVITO requires for 3d rendering of spherical particles. However, it is difficult to say exactly what the cause is from a distance. We only observe that this model series exhibits similar problems.
The Radeon 8000 series is hardware that is already more than 11 years old. I’m afraid we as developers of OVITO can’t do much to achieve compatibility - also because we lack access to appropriate hardware for testing. I’m sorry about that.
If you are an expert, you could also try setting the environment variable OVITO_DISABLE_GEOMETRY_SHADERS=1. This will tell OVITO to refrain from using a particular OpenGL function. Perhaps this will help.
