[SOLVED] How do I change tile placement / snapping?

My tiles are 16x16. My grid height and width is 8. I'd like my tiles to snap on increments of 8 rather than 16. All my objects/sprites do, but not my tilemap.

The issue is I lay down solid objects for collision and then use a tilemap over that. I'd prefer to use this method. With my tiles only being able to snap at 16, it causes issues when I can lay objects out at increments of 8.

Okay I figured it out!

For my collision objects (purple), I needed to have the origin point set to the upper left.

Then with my grid set at 16x16 with snapping on, everything lined up perfectly!
