System Information
Operating system: Windows-10-10.0.19043-SP0 64 Bits
Graphics card: NVIDIA GeForce GTX 1650/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 536.40

Blender Version
Broken: version: 4.0.0 Alpha, branch: main, commit date: 2023-07-28 20:51, hash: 22206a159282
Worked: (newest version of Blender that worked as expected)

Short description of error
Sculpt Mode has it's own pivot point, which you can set in 4.0 with new shortcut Shift - RMB. But when you exit the sculpt mode and enter again sculpt pivot points resets to object origin point, it is not saved.

Exact steps for others to reproduce the error

Enter sculpt mode on Mesh and choose one of the transform tools (Grab, Scale, Rotate)
Set pivot point with Shift RMB
Go to object mode and back to sculpt mode

Can confirm it resets when goes back to sculpt mode.

The data is stored in ob->sculpt which is lost when goes out of sculpt mode. Not sure if we could replace/reuse 3D cursor for this purpose.

There was discussion way back about that at Blenderartists with Joe and users all unanimously preferred 3D cursor for that task. But Joe didn't want to allow 3D cursor in Sculpt Mode. Would be great if that was revisited again

This has always been like this.
Former sculpt developer pablo dobarro once made a patch for proper sculpt pivot manipulation. What happened to it? Died in the old site?
That would eliminate all sort of hacks with 3d cursor in sculpt mode.
This needs to be solved properly with that patch.

Yes, the patch is on the old site, but it's still accessible...
Sculpt: Option to transform only the sculpt pivot
Just needs someone to take over...

I believe this is largely due to that the pivot point needs to be transformed with geometry and that's not how 3D cursor works.

@JosephEagar I saw D9450 seems to be passing eventually, I think I can make a patch for latest main if you don't have anything against the implementation

@ChengduLittleA Hi, I believe Joseph is not around anymore. If I were you I would move forward and make the patch and see how it goes. Besides, by looking at the old site, I can see that Joseph was in favour of implementing the patch as it is. So I guess it's fine.

And thanks for looking at it. That feature is really essential in sculpt mode.

@ChengduLittleA There's an old task to collect these issues and to do's but it's not complete (#80392). Currently there's nobody working on this feature, but small fixes & additions are welcome!
