How Do You Invert Polygroup Visibility in ZBrush?

To invert polygroup visibility in ZBrush, Ctrl+Shift+click on a visible polygroup when only one polygroup is visible. This action will hide the visible polygroup and reveal all the hidden ones.

Here's a more detailed explanation:

1. Selecting a Polygroup: To initially select a polygroup, hold down Ctrl + Shift and click on the specific polygroup you want to isolate or make visible. This isolates that polygroup and hides the rest.

2. Inverting Visibility: If only one polygroup is currently visible (as a result of the previous step), then holding Ctrl + Shift and clicking on that single visible polygroup will invert the visibility. This means the currently visible polygroup will be hidden, and all the other polygroups that were previously hidden will become visible. Essentially, it's a quick way to toggle the visibility of the selected polygroup and the rest of the model.

This technique provides a fast and efficient way to switch between focusing on a single polygroup and viewing the entire model with all its polygroups.
