Zbrush | How to clear 2.5D Canvas and turn it into 3D Canvas

Click and Drag down on the background.

Shift F to turn on Polyframe. Hmm..I forgot to press Edit. Never mind let’s start again.

It’s in 2.5 D that’s why I can’t turn on Polyframe. So I need to clear the canvas. Ctrl / Cmd N.

Click and Drag down on the canvas again and Press T to edit.

then click on Make Polymesh3D.
