Works fine!
I want to order a couple of improvements.
Setting one liquid surface for several indoor groups. (Example implemented as creating several liquids on export, filled by wmo group selection box)
Support for complex surfaces. (Because, a liquid surface in first indoor group, sometimes, emerges through the outdoor group mesh, and be visible from world)

On export, all luquid suface mesh in scene, always take wrong position - one of her corners placed on 0.0.0 coordinate.
