You need to be more descriptive in your BUG report. Part of the model not showing up?? Was it there and a BUG caused it to disappear?
Why is “hair parts missing” a BUG in the app?
If you sculpted this then add in the missing hair parts yourself. Doesn’t look like a BUG.
If you downloaded this then contact the original modeller and ask them what’s up. Doesn’t seem like a BUG
