Retopology - Prevent points snapping through to other side?

[DustyShinigami]

I don't suppose there's a way of preventing points/geo from automatically snapping to points that are behind it? I'm working on an item of clothing and I've had to add thickness. The problem is, every time I re-add/build the geo on the front, it keeps snapping to the geo behind. You can usually see/feel that snap when directly over a point behind, at which point you have to place it out the way, but sometimes it can still force it to snap through. I've tried unticking Auto Snap, changing the Snap type, and I have backface culling enabled, but nothing seems to work.

Thanks

Is this in 2025 or 2026?

EDIT: Wait, never mind. I thought it was a totally different Snap option from its drop-down list. You mean to enable Snap to Closest Normal and add Additional Extrusion...?

yes, try this

but if the model is very small or the front and back faces are very close... will be a difficult task

Okay. I suspect I may have to do it in Maya. I did try adding a bit more thickness this time, but yeah, the edges/distance is fairly close. Thanks.
