[BUG] objects not painting inside brush

[xxwassyxx]

Godot version
4.3

Plugin version
spatial gardener - 1.3.3
terrain3d - 0.9.3a

Platform
Ubuntu 24.04

Issue description
I noticed that the brush does not appear to work as on the tutorials. Looking in the tutorials objects get painted inside the brush sphere. However I noticed with terrain3d it appears to paint exclusively outside the sphere. Almost like its painting the negative space thats left outside of the brush. Collision is enabled and I have made sure that its on the right collision layer. I had to set Collision mode to full/editor for spacial gardener to honor the collision layer of the terrain. Even tried restarting the godot project to see f that made a difference. This only seems to happen on terrain3d to btw, not other objects. Maybe I am simply misunderstanding something so apologies. I looked through all the issues couldn't find something similar.

Steps to Reproduce

1. Create a project. Install terrain3d and spacial gardener.
2. create terrain texture
3. set collision mode top full/editor
4. paint a mesh onto the terrain
