does this work for KSP 1.12?

Is this still working with KSP latest updates ? I installed it with RSS but I'm barely able to reach orbit even with huge rockets and very small payload, and not able to reach the Moon or other planetSs

I haven't got my RSS install upgraded to 1.12.5 yet, but I just tried SMURFF in my test install and it seems to be working.  As a quick test, if you load up the stock Kerbal X in the VAB, it should give you 8850 m/s with SMURFF, compared to 'only' 6428 m/s in the stock game.

Even with SMURFF, you'll still need to make pretty substantial rockets to get into space, and even more so to go interplanetary -- approximately 9.5 km/s of delta-V to get into Earth orbit (you only need 3.5 km/s or so for Kerbin), plus another 3+ km/s to escape.  The Saturn V had a launch mass of nearly 3,000 tons (compare to 130 tons for the Kerbal X) to put about 140 tons into Earth orbit and send 44 tons towards the Moon, of which 15 tons landed on the Moon and 5 came back to Earth.

Hi.

I'm having some trouble getting it to work. It seems to not patch any of the stock fuel tanks or engines.

KSP.log

 

Edit: Looks like an incompatibility with Rational Resources. I'm using these:

RationalResources

RationalResourcesCompanion

RationalResourcesSquad

RationalResourcesSSPXRTanks

RationalResourcesTACLS

 

If I had to guess, I would imagine it's an incompatibility with the RationalResourcesSquad module.

Any help would be appreciated!

You can try the Transmogrifier mod, which is an extension of SMURFf (in my sig). It’ll rescale basic rocket parts to real scale/volume.

probably won’t work with procedural style parts though.

Is there any mod that makes the tanks not behave as tough as. . .  a tank?  The parts in this game seem pretty impervious to destruction. I'm going to guess this is a compromise/limitation of how the game doesn't seem to model materials (at all?). I'm guessing it also doesn't really account for twisting vs bending vs shearing types of forces that can act on them.

Yes, it's a game engine limitation and there is no mod afaik that "fixes" it. The only thing we have is the vanilla joint rigidity but even that is faulty, that's why we have to use the Kerbal Joint Reinforcement mod. Even in the realism overhaul mod you can put an entire Saturn V on top of a space shuttle orange super lightweight tank, or massive weights attached to the side of balloon tanks, and accelerate them to 10G with no worries. I guess we can only simulate realism up to a certain extent, and beyond that, we can only pretend (or live with the guilt, your choice).

Hey @Kerbas_ad_astra, does SMURFF work with Artemis Construction Kit or does anyone know? 

[pinwheel]

It didn't take effect on some mod parts, the fuel tanks are still the original mass

[pinwheel]

It seems to come from mods like "Near Future Launch Vehicles", all mods that modify fuel tanks don't work on them

I think this will solve itself when you install CryoTanks.

It seems to be in effect, but the parts page doesn't show the quality correctly, my oversight!

Is SMURFF not compatible with Cryoengines and Cryotanks? They seem to have way less deltaV than the stock engines.

I intended for SMURFF to work with those mods, there's some code specifically to handle them -- but it's also possible something broke while I've been away.  One thing that's tricky about LH2 is that it's very low-density, so you need much bigger tanks to hold a comparable mass of fuel.  If you just swap out the tank type in-place, there will be less fuel and therefore (possibly) less delta-V, even with the higher Isp.  The way to be sure is to add tanks until the total mass is the same as the original LF/O vehicle, and then compare delta-V.
