I’m not getting any action with the Space Mouse (Wireless, Win11) in the new WIP. I just upgraded my 3dxware also, so it could be that, but it is working properly in Rhino 8.
I’m also getting an Unknown Command when I try to use the SpaceMouse command.
Same issue here
You’re not alone! Already raised in URGENT! Space Mouse isn't working after latest build
Thanks for reporting this. We have indeed been mucking about with the SpaceMouse integration in the RhinoWIP. I’m curious:
If you go to to Options > Advanced and find the Rhino.Options.SpaceBall.UseLegacy what value is it set to? true or false?
Mine is set to False. Changing it to True and restarting the WIP restores SpaceMouse functionality.
Thanks for verifying that. Yeah, clearly we have more work to do on the Windows side. We’re going to respect non-default options values going forward - ie: we won’t ignore that change from false to true 
- so once we get this plugin loading sorted out you might have to opt-in to try the new stuff. Please chalk this up as an early-adopter annoyance.
Sorry for the hiccups, glad the fallback older version is working again.
Would be great if you could make that fix fairly prominent, whenever it is implemented.
Maybe checking on false / true and suggesting the change?
Or just clearly pointing it out.
Or simply resetting to true on every build?
I’m afraid this might go unnoticed, whenever you get the shiny new stuff implemented 
It seems to me that rotation (roll) of the space mouse is still ignored in WIP even after the workaround. I’m clicking enable/disable in the app and it doesn’t seem to matter…
But maybe it’s because I’ve been forced to Factory Reset my WIP a number of times and forgotten how I enabled roll in V8, I’m not sure…
The guys who wrote Rhino 6. Prior to that there were SpaceMouse settings in Options.
Yes, it just shows the standard 3dConnexion options, not the Rhino tailored ones. My guess is that you won’t see the tailored options until McNeel have finished whatever they are doing to the software. You have to use the Rhino SpaceMouse command to get to them for now.
I don’t see that here - but I have done in the past. Unfortunately I can’t recall if I did anything specific to cure it. Maybe unticking all the Reverse boxes, changing Navigation mode then rebooting, followed by changing back and rebooting again. Or rotating three full circles on the office chair while chanting “Save the Rhino” - I dunno, sorry.
I think the inversion issue is just because the spacemouse itself uses camera/dolly mode as default, with object mode just being the same with everything inverted
Same positive restoration of the Spacemouse,
Set Options > Advanced and find the Rhino.Options.SpaceBall.UseLegacy from false to true and restarted.

What “new stuff” are you guys thinking about?
