Why would you need two physics spheres for something as small as a book? Seems like just setting the rest axes alone would have solved things.

I agree with ZB, the two spheres is probably unnecessary in that case, but doesn't hurt anything either.

Well, as NV notes in the first post, if one of the physics spheres goes into solid the whole setup looks worse than if there was just one physics sphere in the first place. Probably why Looking Glass didn't make use of it.

I tried the rest axes first, and only moved onto trying this tutorial after that didn't work. Once I'd figured it needed to be the archetype that had the settings, I never went back and tried it with one physics model again - but it probably works just fine.

As you can see, the use of additional submodels greatly increases the realism of certain objects, even if it can take a bit of experimentation to get all the properties right.
Make note, however, that the player can drop items in such a way as to have their lower phyiscal model appear inside a solid, which causes it to be ignored, and the object to drop to the higher sphere.
since this approach got brought up in the discord again today, i decided to try it out. it took less than a minute of playing around with a shovel set up in this way—dropping it on various terrain, throwing it around—for it to clip through the floor or walls. this was easy to repeat, although sometimes it would sink slowly through the floor instead of suddenly vanishing.
it is very clear that this approach is an unintended side effect of the physics model design, and that multiple sphere submodels was only intended for use with e.g. AIs, where the submodels are managed directly not being physically simulated. even when not falling through the floor, a shovel set up like this shows erratic behaviour, juddering as it rotates, rotating and sliding weirdly when the two submodels are both colliding.
it is clear to me that this setup is much too unreliable for use in a mission.
