Regarding 1) There is no requirement for the simulated world to be a 1:1 mapping of our world. It can be completely different, a simplified subset or whatever it likes; this does not change the premise that to the inhabitants of that world, it is real. Its not our world, but that has no relevance to anything, there is no rule that says it has to be a 1:1 mapping.
As for 2) likewise, randomness isn't a requirement, you're arbitrarily picking one quality and saying that quality has to be identical for it to be real. why? I don't believe that for a second.
I'm fully aware of the simplifications of simulation... being simplified compared to an external universe does not change the premise of it being real to its inhabitants.
Quantum Mechanics does not say that the universe is not mechanistic, just that there is a random element (that in itself may ultimately be modelled).
you're mixing your frames of reference....
The simulated 'moisture' would exist within the simulated universe using simulated water and simulated fabric (for example).
Within the simulation, that fabric would be just as moist as a piece of cloth left out in the rain in our universe.
you can't mix your frames of reference.
