Vessels fall through ground upon loading

[meltingSnowdrift]

KSP.log

PRE version is 1.12. KSP version is 1.7.0. It is not obvious whether they fall through the ground immediately upon loading or very shortly thereafter.

Another log is attached here:
KSP.log

This one was taken just after the falling began but before any subsequent events. The falling vessel is named "# technical 2". The active vessel is named "Sapling A test". In this test, the extended physics range was set to 5km to eliminate any possible effects unique to long ranges. Behaviour does not seem to differ at all from my earlier longer-range tests.

Regarding the standard long range test. Would you mind to describe the scenario in which the landed vessel went through the ground?

Also would to mind to copy & paste presettings?

[meltingSnowdrift]

In the original tests, extended physics range was set to various settings between 100km and 30km, with the exact setting not affecting the result. I placed a truck and a (landed) small aircraft on the large round island northeast of the KSC. I then took off from KSC and flew toward the island. Upon entering physics range, each of the objects fell through the ground.

What is meant by "presettings"? If you meant the settings.cfg file from GameData, here:

PreSettings
{
	GlobalRange = 5
	ModEnabled = True
	CamFixMultiplier = 1
	TerrainExtenderEnabled = True
}

GlobalRange was set to 5 from the last test.

Both falling vessels had non-stock wheels. The truck used wheels using the KSPWheel mod and the light aircraft had landing gear that was from a mod but was of the standard type. If you want, I can conduct additional tests with purely stock landing gear or various alternative arrangements of ground contact.

Hi!

Would you mind to perform some testing using the latest release using the standard 100 km range? https://github.com/jrodrigv/PhysicsRangeExtender/releases/tag/1.13.0

[meltingSnowdrift]

Okay. Should I do so immediately using the release zip file or should I wait for it to become available on CKAN and install it that way?

[jrodrigv]

You can use the zip file

It fell through the ground in the test you specified. The vessel name of the fallen vessel is "Chopstick B". Another vessel "# technical 2", which uses parts with non-stock wheel colliders, also fell when entering physics range.

You may ask me for any additional information about my setup. You may also request videos depicting specific tests.

Some more testing has revealed more serious issues.

Fired torpedoes stop moving when switching to a distant (but in extended physics range) vessel and back. This appears to happen whenever the player-controlled vessel becomes more than about 350m away from a torpedo. The torpedoes start moving again when I drive the launching vessel (or presumably any vessel with focus) to within about 200m of them. I have possibly also observed ships and submarines becoming stopped in the water in similar cases.

Additionally, ground vehicles seem to disappear from the BDA vessel switch list as well as the BDA wing command interface when more than a short distance away, a distance similar to those described above. When in this state, BDA guard mode does not recognize them as targets.

Thank you very much for you testing. I will keep you updated

[jrodrigv]

Would you mind to record some videos whenever you have time? It would help me a lot so I can replicate the same scenarios. El mar., 25 jun. 2019 a las 6:03, meltingSnowdrift (< notifications@github.com>) escribió:

Hi,
I have found an issue and fixed it. I have done several tests, one reducing the range to 25 km and having a vessel landed on the island. Then flying a plane from KSC to the island.

The vessel on the Island is properly loaded, focused, lifted and landed again.

PhysicsRangeExtender.1.13_06242019_hotfix.zip

[meltingSnowdrift]

Results of test with physics range set to 100km:
Upon getting to within physics range of the two vessels on the island, the game began repeatedly switching between each of those two vessels and my vessel and occasionally displaying loading screens. The two new vessels were repeatedly lifted. This went in a cycle for a long time. Eventually, while I was not paying attention to what was exactly happening any more, a splash was heard and focus moved to another vessel which had been loaded at the beginning. The F3 dialog informed me that my aircraft had hit the water and was destroyed.
KSP.log

Results for 25km range test:
The aircraft disappeared upon getting into range of the vessels on the ground. Instead of trying to describe in words everything that happened, I made a video.

Please make the hotfix a release if a complete fix is expected to take a long time. Despite the events described above, it seems from further experience somewhat less broken than the main 1.13 release. Again, if you want me to do more testing, including in alternate configurations with less mods, you are welcome to ask me here.

[jrodrigv]

Hi,

I just published a new release with I hope fixes most part of the critical issues on the previous version. Would you mind to give it a go?

https://github.com/jrodrigv/PhysicsRangeExtender/releases/tag/1.14.0

Thanks in advance

[meltingSnowdrift]

I have conducted a test after installing it. Very similar bugs persist. Again, instead of trying to explain what happened in words, here is a video. https://youtu.be/3be2a8pRq-M

Here is the log from the same test if it helps.
