Hi everyone
I am working on a plane project and I have been running into an issue lately.
When I try to rotate the plane, it rotates from a pivot point under plane itself which gives it a weird effect.
This is my blueprint:
You just need to move everything in the blueprint so that pivot ( which is at 0,0,0 ) is in the right place.
you can use a scene component as the parent and adjust all children relative to it. I may be saying same thing as clockwork ocean but am not sure so figured iâd chime in.
I canât move the box collision down since itâs the root, I tried moving the rest but that didnât fix it, got anything I can do to fix that?
I canât do that because it needs to simulate physics, I tried to but it didnât work 
Do you have the 3D Model as OBJ or FBX or anything similar?
If yes - import it in a 3D Modelling Software, move to the Center as you need and the Center is the Pivot Point
Export from 3D Modelling Software and import to UE4 back - now you have your mesh as intended
Edit: Or wait⌠
you mean the whole BP pivot point? itâs always the Center where the Root is
Why do you want the Box as root?
You can f.ex. use the Plane and its collision (if it doesnât have any you can generate it in UE)
Or do you have any particular reason for that setup where the box is the Root Component?
But if you just rotate the Plane then I assume the Plane itself has Pivot Point underneath so you probably need my 1st idea solution 
Also be aware that if the Box is not moved and itâs the Root - itâs always gonna stay in Place
Is that intended? Actually you could use that as the landing point afterwards as an example 
the reason the box component is root is because I canât use the skeletal mesh as root for the reason that I canât add a force to it or it will give an error, so thatâs how I fixed that error and now it works. If you know any other workarounds, it would be greatly appreciated.
I wonder why epic hasnât added this yet.
And no, sadly I donât have an OBJ or OBX file of the planeâŚ
Read the middle line
If I select the existing âSkeletal Cubeâ itâs disabled
But if I select the âSK Mannequinâ it is available:
And this is because your Plane doesnât have Physics Collision setup, it looks like this:
And you can get there just by double clicking the Skeletal Mesh
I hope that clarifies it
Yeah I tried that and I can enable physics, but as soon as I use the addforce node, I get an error and everything stops working for some weird reason
Then double click the Plane Skeletal Mesh and tell me if:
A - it looks like this:
or B - like this:
Top Right corner
In the Plane BP - what is the Collision Preset for the Plane Skeletal Mesh?
It should be PhysicsActor in your case
Look, I made my guy flying while having physics on xD
And thatâs what I did to him:
And If I select the Bone to Head he will ascend to the Heavens XD
Itâs currently set to nocollision, I tried the others too
No Collision returns error âPhysics enabled but collision incompatibleâ
When changed to PhysicsActor it should work as intended
Make sure you select the correct bone IF none (Root) isnât what you need
If thereâs no - you can add own
Iâll come back to this tomorrow cause itâs really late right now, thanks for the help!
No problem
Just please give a feedback after all, or just ask if youâre still stuck
Wish you best of luck! Although itâs not as hard as you thing - it just exists and works only when some rules are met, thatâs it ;]
Hi again, I just removed the box again, set simulate physics to true on the skeletal mesh, changed the collision to physics body and tried to specify a bone for the addforce and addtorque node, I get no errors but physics donât seem to be working, did I miss something?
when I remove the bone from the nodes, I just get an error that physics need to be enabled.
Iâll try some more stuff now.
Edit: Iâll try copying the code to the mannequin
I found out itâs definitely the plane because it works fine with the character untill I change the skeletalmesh to the plane, and it just doesnât work anymore
I managed to make him stand up just by adding a force to his head 
Youâre using UE5 unfortunately, and you donât have the Plane Model as ârawâ model
If you have UE4.26/7 - migrate the Plane to such Project and send me the UASSET file
Hereâs some Rigged Plane for free, maybe it will do
And some tutorial (UE4) on how to add Collisions to Skeletal Meshes which is a mandatory for physics to work
Although for UE4 - the principle should be pretty same as for UE5, it may be that you just have to look for some stuff in different areas
Be careful with UE5 and simulate physics, itâs bugged and the fix is planned for 5.1 release.
To make an example of what Iâm talking about: Move Objects On Conveyor Belt UE5
