Thank you for your feedback Root cause: nVidia GTX 9 & 10 series display card has the "ROV" feature, but there is a ROV defect in recent updated driver witch will cause iClone to crash. We can only bypass this error for now, but there are still a few cases that cannot be solved. If you are using GTX 9/10 series display card and having the following issues in iClone 7.21: * Freezing issue while rendering video. * Crash caused by Billboards contents. Please do the following steps for the workaround: 1. Download this zip file: https://drive.google.com/open?id=1SmpkoGXXHpEpRbUY9_wjthkYIA6PRDJk 2. Unzip, and run the IC-7-Rov-OFF.reg to turn off the ROV feature in iClone. 3. Restart iClone. We will update iClone to avoid the crash caused by ROV issue in next patch. Reallusion
I can confirm this on my system.
