Following the removing full expression Reallusion guide, provokes a crash and project restoration.
In order to reproduce the issue, I create a Motion Live expression clip (using iPhone Live Face), then I try to reset the expression using Face Puppet.
SUGGESTION: It would be nice to have a key shortcut instead of must following a guide, to simply reset character expression. Or even better, you could make optional to automatically reset face expressions at the end of a face clip (puppet or motion live).
