Any idea what can I do?
Hi…
Have you tried with the free sample characters that come with AccuRig?
If you don’t have a problem with these three characters (available from the File menu) then that would indicate the custom character you are trying to rig as being the problem.
However, if the issue is with all characters you try to rig, then check your graphics drivers are up to date as this could be causing the problem.
You might also like to uninstall AccuRig and then download and install the latest version afresh as there may be an issue with your current installation.
