Hi,
The shape field converts a signed distance field (for example a Vectron or Volume SDF node) into a weight field. The values in the interior of the shape are set to 1.0 and the values on the exterior fall off until they reach 0.0 at the Falloff distance. This can be used to shape a 3D gradient into an arbitrary Vectron surface and use it as an effector in world space.
The shape field basically takes a slice of an object and sets the color from black to white depending on the distance to the borders of the object on this slice.
You have to adjust the UVW transform of the shape field to move and scale the slice in the object.
Using a MeshVolume object, it seems to work better with a low-resolution grid.
