Kerbal Space Program

The problem is still there in 1.1.2 and it quite annoying and and can be game breaking when one tries to build a surface base.

It seems there is no static friction in KSP at all and things are never at rest when on any slope. Various factors seem to influence this (terrain slope being the most obvious), sometimes quite counter-intuitive – e.g. deploying drills raises the base and makes slide it faster.

Easy proof: land something on a Mün slope, set a waypoint where it stand (using WaypointManager mod, maybe there is a stock way do note exact coordinates) and keep the physics running. No time wrap or unloading/loading of the craft needed, though it speeds things up.

I can confirm this as well, and I don't use mechjeb. I'm having problems with everything sliding on Eve, and none of my design attempts have been able to stop it. It happens with both 1 ton rovers and 400 ton landers. Objects resting on wheels/legs seem to slide more, but even the lander sitting directly on it's engines slowly creeps along the ground. I consider this a pretty serious bug because it makes any surface mission longer than planting a flag and picking up some dirt impossible.

Isn't it possible to just put back the old lander legs? i have problems with sliding landed craft in most bodies with just a minimal slope... this is really annoying, and has been since the 1.1 update!!!!!!!!!!! ..... i have literally to run after ships if i try to EVA. although funny at first, it gets old fast.

also on a related leg issue, in attempts to slow down the sliding ive raised the legs and then deployed them again, resulting in the ship beign launched into the air with violence... then away from the ground ive noticed the legs now deploy with a sudden motion, i dont remember this motion in legs before 1.1

im sry im reporting this now, its just i was part of the lucky ones that CTDed in VAB 1.1 through 1.1.3

I have confirmed that this is still an issue. This is really putting a damper on game play as I am at a point in my space program where I'm building bases. Has there been any movement on this ticket? Any possibility of bumping it up in priority as it does break a significant aspect of game play pertaining to advanced in game space programs? Also can we have an ETA on the fix of this issue if possible?

Thank you for your attention to this issue.

Hello, just checking in to see what the status of this bug is. This bug has been out there for nearly a year now. As a previous person on this issue mentioned, it is a fairly serious bug as it does dramatically limit surface missions. Can we get an update on this bug? I'm rather disappointed that no one responded to my previous post answering my questions.

This is a bug in the fundamental physics package that Unity (and therefore KSP) uses, called PhysX -- which is closed-source code maintained by NVidia. The problem is that everything bounces constantly. I call it microbouncing. Nothing ever comes to rest. Most things spend 90% of their time .0001 meters above the ground during the bounces, and there is no surface friction while things are bouncing in the air. The devs have added countless kludges to minimize the size of the bounces, but they are unable to eliminate it. So yes, everything bounces and moves and slides, and there's not a darn thing we can do about it until NVidia fixes PhysX, or until KSP dumps Unity and switches to an entirely different library (which would involve a big rewrite). Squad has been expecting that PhysX will be fixed eventually, but we all agree it's a big problem and Squad will not wait forever either.

But it "used" to work. Somewhere around 1.05 it got broke, is there no way to roll this back to a version of physx that works?
