I was working in a new model but when I tried to save it I had a memory problem and zbrush suddenly closed.
When I try to load my model back it says
error while reading highdef data object
Is there any way to recover my model.
Help me please!!!

Unfortunately, there’s not. Once a model has become corrupted, it’s gone.
I strongly recommend using SubTool Master to save your models. Also, make sure that your Preferences>Mem settings are appropriate to your computer.
Thanks aurick for answer.
