You get a lot more out of a few sets of bricks, stones, etc. For the more random-looking materials, like the stone wall you…

Correct me if I am wrong but the main idea that he is showing is this: 1. Instead of laying down your brick/tile pattern on the "destructive" 2.5 canvas you export them using a lower subdiv level to a 3D program where you can use the grid to lay down your patterns. 2. Export back into Zbrush and turn the subdiv. on and do…
