Moving the mouse in units on the terrain when painting?

[Jamie_Sandell]

When Rick is painting the terrain, you can see from around 07:40 when he moves his mouse pointer it moves in what looks to be a unit scale/grid like fashion.
How does he do this? I’m following along but my mouse is moving in a continuous movement.

Here’s an image of what Rick is doing.

@Rick_Davidson I honestly cant remember this one!

I think you’re referring to the cursor snapping to the grid. You can tweak your “snap to grid” settings to make your cursor do this too.
