How do I change the snap grid for probuilder?

I know I can hold down ctrl to move selected things in increments of one meter. How do I change that step size to be less than that? Such as 0.1m?

 

Hi @PeterCym,

You probably need to adjust your project's snap settings in Edit/Grid and Snap settings.
There is the option Increment Snap. Change it from 1 meter to something lower.

And when using ProBuilder, I would also install ProGrids via the Package Manager. Then you have snap settings for modeling that don't require you to press control etc., just toggle snap on.
