Why can't I see the complete Face Tools UI in ZB?

The character looks different in CC and ZBrush after several rounds of Relink and Update.

The diffuse texture looks different between ZBrush and CC.

Unexpected border lines appear when wrinkle diffuse textures are updated in CC from ZBrush.

Adjusting polypaint in ZBrush leads to artifacts in the texture map.

Polygroups assigned above Subdiv 1 do not yield accurate results upon relinking.

The polyframe diverges from the original appearance in Subdivision Level 1 after relinking the CC character to ZBrush above the base subdivision level.

Use-cases for Reset Face Tools

The diffuse map automatically gets replaced when the Refresh Face Tools button is pressed.

After the CC character is sent to ZBrush, the wrinkle diffuse texture becomes pure white when an expression is picked.
