What I’m trying to achieve is a way to mix various functions by having them be covered by a mesh collection however so far my node set up can only recognise the edges so I’m looking to see if there is a way to force Geometry Proximity to recognise volume enter image description here

  • $\begingroup$ no im actually trying to make a sort of brush. For context im making a terrain generator and I had an idea of making feature a where you place boundary boxes around certain parts then it applies a displacements and materials and that’s working so far but as you can see in this instance I have a ring from the perimeter of sphere mesh then I need a filled in dot. $\endgroup$

You can use this setup to check if object inside volume (by checking normal direction) and combine it with face proximity

This is how to check for selections (if one mesh is inside another):

And this is how to get an SDF:

If you want the distance from the object but not a negative distance inside (like an SDF hase), you could set the inside to be 0. Like this: enter image description here this will visually look the same as an sdf in the viewport, because blender (or computers) don't display negative values anyway.

Here is a useful nodegroup you could make:
