  1. so following a previous suggestion I have reverted to - in which was installed by ckan on 6/27/2022, after a few minutes of play I am unable to save any games, and autosave isn't working either. F5 doesn't work, alt-F5 manual save causes the entire game to crash, plus when this happens I cannot go back to tracking station/space center - seems like the bug y'all are talking about. My log is full of this when I try any of these operations: [EXC 19:43:20.256] ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

  2. so I installed this off CKAN and it seems some of the parts are missing; I see someone else had this problem, although the parts appear to be in the gamedata folder, I can't find like the engines, landing gear, or the piece that attaches between the cockpit and the docking port/rcs nose - must this be manually installed or is there a way to fix a ckan install? or am I just missing something in my part search (I have a lot of other mods)... would be cool if it supported modular fuel tanks too, I might be able to whip up a patch file for MM to allow that (ie, I'd like to attach KSPIE thermal antimatter engines to it because why not, and I need HTP ejection mass for that)
  3. 1. the kerbstein drive is its own fusion reactor - you need to have something else as well to initiate fusion, however, such as at minimum a fission reactor and an appropriate thermal generator. The kerbstein will produce electrical power when it's online however - keep in mind the drive cannot operate before about 50km altitude on kerbin (can operate in any vacuum, it's an atmosphere thing, not a gravity thing ) 2. a lot of the KSPIE parts don't have a 'next propellant' button - look for a 'switch window' button, that will let you pick the container contents from a list
  4. I've taken a very manual approach... enter a stable orbit at a fixed altitude such as 100km, F5 to save. come up with a consistent procedure ie de-orbit burn, destage N number of times, ensure re-entry vector is set as SVEL- or fixed pitch and heading, ensure a consistent periapsis for deorbit braking... write all that down.. then note the lat/lon at the point of initiating the deorbit burn. Then note the lat/lon of the landing point. calculate the distance required. Then calculate the exact lat/lon to start the burn for a KSC landing. Of course this has to be done separately for each craft (or at least weight/re-entry profile) and it takes a while. Looking forward to your potential new update with multi-stage calculation
  5. KRAMAX Autopilot and MechJeb2 also have the ability to display lat/lon for your current position and certain targets/waypoints. So,. question on usability; generally you'll have a deorbit burn, and then you have to decouple things for your final re-entry config; I see from the top page of this thread that Trajectories cannot predict for future stages, so.. how is everyone actually using this mod? When you decouple the last stage, it sheds a bunch of weight, which alters the trajectory significantly; I'm sure that all of you who have been using Trajectories for a while have come up with a way to make this mod be functionally useful, I'd like to hear your thoughts, given this limitation?
  6. @Starwaster what information could I gather that would allow you, or me, or someone, to add a patch to DRE to support those parts? KSPIE radiators are either titanium or graphene high temperature radiators designed to cool high energy fusion and antimatter reactions, so they have, in theory, pretty high limits. They support the concept of both convection heat transfer (usually in atmosphere, and the titanium radiators are better than graphene for this), and radiant heat transfer (usually in vacuum, using graphene).
  7. I've noticed with this mod that when KSPIE radiators get hot, they appear to catch on fire and trail fire behind the radiators - often this is harmless as these things hold a ton of heat safely, but it seems something is miscalibrated? Also the fire effects persist *in vacuum* which doesn't seem possible? Is there a configuration setting for this? or is KSPIE incompatible with this mod?
  8. @Grumpy_Bud crashing into things or running out of power will cause antimatter tanks to explode. Antimatter is confined away from matter by the use of powerful electromagnets. If you run out of power, antimatter confinement fails, and the antimatter touches matter, and BOOM. @FreeThinker separate issue here: I'm having a weird issue with propulsion on Eve. It's almost like the positron-antimatter reactors have a maximum air pressure in which they'll operate. I have a craft powered by 2 positron reactors and 4 VTOL pelican(?) thermal turbojets.. the ones that swivel.. anyways, this craft, using TCA, is a brilliant long-range landing craft and I have successfully planted a flag with it on every solid body I can find. Except Eve. When I get into Eve's lower atmosphere, everything stops working, the engines, the RCS, etc. I can land with a parachute, but I can't take off again. If I quicksave/quickload at this point, I get a unity crash. If I restart the game and reload the save, with the craft landed on Eve, immediate Unity crash in that case as well. Craft works fine on Kerbin, Duna, and Laythe - but Eve has a lot more atmospheric pressure. Weirdly, there's one thing that kinda works... the craft has the 4 engines which when deployed, point down. when retracted, 2 point aft, 2 point forward, so you can thrust in any direction, or VTOL. if, after landing on Eve, I activate only one of these groups of engines, and have them retracted (ie, not pointing downward), they'll generate thrust, but if both are activated or if any of them are pointed downward, they will not. I've also noticed that my reaction wheels appear to not be working while landed, and that's why I'm thinking it's a reactor/generator issue in the high pressure atmosphere.. so, is this a bug or is this working as intended and I need a different power source for Eve? I know I've landed on Eve before with these engines, years ago in previous versions of KSP and previous versions of this mod, but.. this is the current state of things. Also tried removing Kopernicus as I'm not currently using it - thought that might be relevant - it was not. I am using FAR, if that makes a difference.
  9. I too use both AA and KRAMAX but it seems like AA does nothing when Kramax is engaged.. I can't notice any difference between AA on/off when kramax is on, at least. I have lately been having a lot of trouble with pitch and sometimes yaw oscillations with kramax - it's gotten worse in the last 12-18 months it seems like - the only designs that are stable in kramax are twin tail (V tail) delta wing designs.. anything with separate wings and elevators seems to be very prone to oscillation, sometimes extreme inputs to the vertical speed PID's scalar value fixes it (like over 4.00) sometimes not. What I cannot find is any QR guide on what the PID tunable values actually do, ie what effect does scalar have (you mentioned it's like a damper, is that it?) what about Kd and Ki and the others? I'm not sure how to figure out what I need to tune and in which direction to stabilize flight. All of the designs in which the oscillations occur, if I turn off KRAMAX and use AA, they fly in a very stable fashion, so I don't think it's a problem with my designs per se, but rather that they require different PID values that I have yet to find. Can one see the AA PID values from anywhere in AA? does copying those PID values into kramax work, by any chance?
  10. so, looking back in the log, there's nothing between the time the craft entered Eve's atmosphere and the time it exploded except for FAR's normal "voxel smoothing" messages. Should I set the loglevel from info to debug to get more? the FarAero config files look reasonable (I think) - anything to check for in there, any in-game settings to look for? maybe just try it again?
  11. so y'all want to see the *entire* log, not just certain relevant parts? anyone had an issue like this before? I've been using FAR almost since I started playing KSP in 2013 and haven't had an issue like this...
  12. so, odd issue, air doesn't.. work.. on eve.. works on kerbin and on duna.. on eve I'm getting the heat and the explosions, but absolutely no aero drag, and the reynolds number shows as "infinity"; what would I be looking for in the logs here that might explain it? I'll paste logs but I don't want to spew irrelevant garbage in here, if someone has any idea of what to look for, that'd be helpful
  13. I have some questions about PID tuning.. some of my craft seem to have a lot of low-speed pitch oscillation when on initial/final approach; I've been solving this by increasing the scalar value for the vertical speed PID but that doesn't always work; is there a smarter way to tune the PIDs? The craft in question all fly in a stable fashion when using fly-by-wire or pure manual control, so i don't think it's a design problem per se, but I'd like some advice on how to tune out the pitch oscillation better than just ramping the scalar up..? Also if there were a way to integrate with FAR such that I could specify approach speeds in KIAS instead of m/s ground speed, that'd also be good, since.. that's how approach speeds work in the real world
  14. can you use kerbal konstructs to place these launchpads on other planets/moons?
