density key doesn't work for subentities.I've got an entity with two subentities which are each identical to the entity. With density = 1 they have a total mass of 480, each of them 160.
Now I gave all of them density = 0.2 and expected 1/5 of 480 = 96. But I got 352. Only explanation: the main entity got the correct density of 0.2 and mass of 32, but the subentities stuck to their mass of 2 * 160 = 320.
I also tried to give the subentities a density > 1, with the same result. The key seems to be ignored altogether for subentities.
EDIT: fixed nonsensical typo; but the problem got fixed anyway
