Dissapearing ships/parts when i separate one from another in suborbital environements

[juvilado]

Hi, i think this is just a game issue, and maybe related to bad programming or optimization but im not sure so i ask.

Lets say i build a two stages rocket, first of it is an air taking engine with its own pilot, the second stage a conventinal rocket with its pilot. When i reach 20km i decide to decouple and ascend with the conventional rocket while the first stage deploys several parachutes for a safe landing (the two ships are manned, so none of them is debris i would swear) but soon one of them (when some distance between them is reached i think), the one im not flying, just vanishes forever. It doesn't happen while in orbit, i wonder it only happens in suborbital environements(?).

My question is: is there any way to avoid this? If not, a reusable air breathing first stage is not viable due to bad game developpement :-(

Any suggestion, advices or oppinions about this?

Thanks

Yeah, physics unload and put anything more than around 22 km from you on rails. And anything on rails below around 22 km is destroyed instantly.

Possible solutions are:

1) Go higher with your reusable stage so you can circularize your main stage and then switch to the reusable portion and land. However, at that point your suborbital trajectory is so far away from KSC that is makes sense to just build an SSTO than can launch the payload and return.

2) Stay with 22 km while the parachutes deploy and land. Good luck with that.

3) I don't use it at the moment, but another option is the Stage Recovery Mod which will recover any stage that would have been destroyed if it has parachutes.

A small update to Cybersol's #2. Use a mod to increase the physics range.

But this will put a higher load on your CPU and can and probably will cause lag.

Do you know how is called that mod?

I don't know any that are guaranteed to work. But I do know all of Romfarer's mods include 'romfarer.dll'. It enabled you to increase the physics bubble to something like 50km. But ... his mods haven't been updated for half a year (0.90) and might not work in 1.0.X.

For your information, im still running in .24.5 ? (last before 1.00) because of the many mods i have installed; i downloaded TTneverunload and it works perfectly for the purpose i was looking for. I totally recommend it!
