Socraticat Posted August 12, 2023 Share Posted August 12, 2023 (edited) As of version 0.1.3.2, Parts without physics seem to be the main issue for many of my inexplicable bugs, so let's make sure everyone knows which parts they are so they can experiment or avoid them. It's tough to be Kraken bait without even knowing what's luring the beast. If you have a part to add to the list, or a combo of parts or assembly that seems to give you issues (or maybe even a workaround), please post it here. Someone mentioned physicsless parts as an issue and the notes in the Wiki are remarkably similar to what I've encountered in KSP2. I've confirmed 2 craft killers from this list and wonder if other parts in this category of attachment could cause problems in certain circumstances. I've grabbed a list of parts from a KSP1 wiki since KSP2 wikis are unfinished (nor can I find a comprehensive part list without making my own). From the Kerbal Wiki for KSP1: Spoiler Physicsless parts are parts where the physics don't work in the usual way. The mass of the part and the drag experienced by it are added to the parent's part. The part itself has no mass nor drag at its point of placement, but it still contributes to the vehicle's total mass and drag; in short, during movement, the added physicless parts would not generate mass-shift and drag that affects lateral stability. Before 1.0.1 the mass and the drag weren't added to the parent but just ignored. It is influenced by the PhysicsSignificance flag in the part configuration which must be set to 1 to make it physicsless. When constructing a craft, the root part can't be such a part. Behavior A craft with only physicsless parts starts to oscillate after a short time and then starts to destroy itself. But this is usually not possible because the root part is always not a physicsless part. The game can change the property on the fly, so that when a new root part after decoupling would be physicsless the game removes that special status.

Until then, I hope this helps you all "Fly Safe"! Edited August 14, 2023 by Socraticat Developing insight/ Clarity Link to comment Share on other sites More sharing options...
Bej Kerman Posted August 13, 2023 Share Posted August 13, 2023 Are you just assuming whatever was physicsless in KSP 1 must behave the exact same way in KSP 2? Link to comment Share on other sites More sharing options...
Socraticat Posted August 14, 2023 Author Share Posted August 14, 2023 (edited) Since I have absolutely no knowledge of how it works otherwise? Yeah. Unless someone can clear that up... Clearly some of thes parts aren't the same in KSP2, but it gives me something to aim at. Having said that, I haven't had trouble with any of these parts EXCEPT for the XS cubic trusses and hubs in experimentation.
