This shader uses the same code from the "3D Vertical Dissolve" shader, but instead of taking the object's global_transform, it uses the object pixel in local space to dissolve, this way, it dissolves from the mesh's real local top-down or bottom-up (when checking Up).

This shader uses the same code from the "3D Vertical Dissolve" shader, but instead of taking the object's global_transform, it uses the object pixel in local space to dissolve, this way, it dissolves from the mesh's real local top-down or bottom-up (for example, "from head to chin" or "from chin to head").
The only change is in
vec3 position = (inverse(WORLD_MATRIX) * CAMERA_MATRIX * vec4(VERTEX, 1.0)).xyz;instead ofvec3 position = world_pos;.This is the final result:
GodotVerticalDissolveObjectSpace.mp4
As a comparison, this is the behaviour of the existing 3D Vertical Dissolve shader, notice after 0:02 when I rotate the mesh, how it's dissolved (it doesn't take into consideration that the "top" is the "head"):
