Check the scaling of crewed parts on KSP 1.11

[Lisias]

As the tittle says.

On KSP 1.11, crewed parts changes mass accordingly its contents.

Kerbals are no longer massless, and the weight they carry in their inventories matters in terms of physics. In order to not impact the way existing vessels fly, an amount of mass equal to the size of the crew times the mass of a kerbal with a full jetpack and a parachute (94kg) is subtracted from the vessel mass and added back in function of the crew in the vessel. This is all already done automatically, but if you want to play around with different mass values for a kerbal, the value is kerbalCrewMass in Physics.cfg (defaults to 45 kg).

A full description of the new status quo can be found in the DevBlogs.

Check how TweakScale behave about this.

-- EDIT --

It works fine. See the last post. :)

So, I took a MK1 Command Pod:

Removed the crew:

And checked the new mass of the now crewless part:

CrewedMass = 0.840t
UncrewedMass = 0.746t
Difference = 0.094t = 94Kg.

Now I scaled the thing up:

And then recrewed it:

And checked the new mass:

ScaledUncrewedMass = 1.724t
ScaledCrewedMass = 1.818t
Difference = 0,094t == 94Kg.

SUCCESS . :)

Verdict: it's safe to scale crewed parts, the way Squad implemented the feature didn't affected TweakScale at Editing Time.

Now I need to check at runtime.

[Lisias]

Yep. It works fine at Flight Time. :)

other than what I think it's a rounding error, the numbers match what we have on VAB/SPH .

No specific action on TweakScale is needed, the new feature caused no regression.

Of course some implementation are needed to support the Inventories on the scaled part (hint: as I did on KISS, allowing the user to scale the compartment size, or the number of compartments), but the scaling itself is working fine,
