Hi @munch_matthieu, please can you let me know which version of DCS World you are using?
Please be aware that if you are using DCS 2.7.7.15038 we have thoroughly tested and unfortunately have not been able to get our Gemini V5 hand tracking working in this by changing or modifying the dll as was possible in previous versions.
If you wish to use our Gemini V5 hand tracking in this version then you will need to wait for an official update from Eagle Dynamics due to the changes in file structure in this version. Please note that you can still use our previous Orion V4 hand tracking in this version of DCS World.
