Airtight voxels

This is an old SE1 desire that I'd like to suggest for SE2, which is that a voxel surface be considered airtight, perhaps by giving us some sort of resin-like material to seal any microfractures or the like. That would allow some greater base design options.

Considering something like

1. Raw cave mode: Sealing off a cave entrance should allow the room to be pressurized, but have the air vent show a warning of some sort as there is a slow air leak due to porosity of the rack material.

2. Sealed material cave mode: Some sort of resin paint that can be used to seal the voxel surfaces and would make the cave fully airsealed.

the raw cave mode slow leak would cause a fairly slow consumption of the base oxygen as though it's having to supply a number of extra occupants beyond your space buddy. Nothing like an explosive depressurization, but just slowly consumes the o2 in tanks as tiny % of the voxel surface leaks into the hostile environment. I would love to be able to just carve a cave and put a door over the opening. A number of oxygen farms would easily be able to offset it.

I would add the possibility to seal rooms using subgrids. Think big hangar doors, boarding ramps, extendable docking mechanisms and so on. And by that I mean without physically merging the movable subgrids to the main grid. Small gap between grids would be considered as a seal basically.

Alternatively, we might need much better merging mechanics. The biggest problem here is being able to unmerge grids when too many blocks are touching without using dozens of merge blocks.

I know we can potentially use an old technique where 2 grids are merged along edges that are touching each other but not actually attached. This is how we did it in SE1. But it is quite challenging and often looks ugly.

We could have something like "magnetic sealing" strips. A couple of different variants, including long strips, so you don't need to place dozens of small blocks along the edge you want to seal. The sealing strip would have atatchment only on one side and all other sides, even if physcially touhing other blcoks are not actually connected to them.

This would be ideal for things like custom glass cockpits, for example.

I think there was a discussion about this in a prior thread, this sounds familiar. Magnetic sealing (or simply inflatable gaskets that seal gaps) would definitely be useful.

In the case of structures built inside of voxels (partly), it's always been a little wonky to have to place blocks essentially inside the voxels to 'seal' them to make an airtight chamber. The two tier approach above would allow you to build in an asteroid without embedding walls, one tier would require constant o2 added into the system to offset the slow leaks, the higher tier would function as normal because the voxel surface was treated by some sort of resin compound. If that area gets drilled again after sealing, then it would start leaking again and drop to the tier 1 state.
