Common problems
Update the NVIDIA driver. An NVIDIA GPU and driver are required, also in CPU only mode.
The GPU is out of memory. Switch to Balanced in the settings. The editor stays open:
press Start Model again.
Check the connection and the free disk space (~9.3 GB), then Retry Download: it resumes where it stopped.
On a drive without short (8.3) file names the model cannot open such a path. Choose another folder with
Change Folder….
Loading the model takes 10–30 seconds after Start Model; the status turns green (Ready) when it is done. Later
generations take a few seconds each.
Open the IK Retargeter generated for the character in
/Game/TextToAnim/Rig and check its chain mapping and
retarget pose. Characters whose skeleton Unreal does not recognize may need their IK Rig fixed by hand.
