Weight paint through object changed in 2.83

I found this solution, but blender 2.83 no longer has those buttons there. Any suggestions?

Hello friend!

I was looking for answers for the same question and I believe I found it after some clicking spray and pray.

Under the brush settings there is a Falloff click down menu. You’ll see the graph- underneath said graph there is the “Falloff Shape”. Its selected as “sphere” as default but if you select “project” than you’ll go through the mesh!

Hope this helps you and any other lurker!
