System Information
Operating system: Windows-10-10.0.22621-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 2070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 531.41

Blender Version
Broken: version: 3.5.0, branch: blender-v3.5-release, commit date: 2023-03-29 02:56, hash: 1be25cfff18b
Worked: (newest version of Blender that worked as expected)

Short description of error

When sculpting with imported brushes in 3.5 when applying an anchored brush (settings the same as in 3.3.5 LTS), the result looks lifted up from the surface.

Caused by disabled "Vector Displacement" option when brushes from 3.3 were appended into 3.5, likely a versioning issue.

The option is added with #104481.

Exact steps for others to reproduce the error

Steps used in both releases:

Add Cube
Add Multisres modifier
Subdivide times 6
Apply modifier
Ctrl-A, origing to Geometry
Append brushes
Go to sculptmode
Choose a brush
Apply brush on object

Using 3.3.5 The brush is nicely put on the object, in 3.5 (with the same settings) you get a pimple. Lowering strength doesn't do the trick in 3.5.

Hi @Ronald-Veldhuizen, I'm not quite sure what the issue is. In the provided files, both 3_3_5 and 3_5 both behaves the same opened with either 3.3 or 3.5:

All the "Draw" brushes in both files are in "Anchor" mode.
If setting any of those brushes to "Space" mode (like default brushes), save the file, then append the brush from a new file, the mode retains "Space".

I'm not sure I understood the problem. It looks to me that all custom brushes in those files you provided are like decals, which are supposed to work in "Anchor" mode, and they do work that way both in 3.3 and 3.5. Is the problem being that you have a brush that used to draw a line across the mesh, while after appended to a new file it behaves like a decal brush?

Hi I made two screencaptures. I hope this will clear things out. In version 3.5 the whole mess is also 'exploding'

Ok I see the problem. You actually meant the decal "moved up" compared to 3.3.5.

The brush texture "Vector Displacement" option in 3.5 is off on appended brushes, that option does not exist in 3.3, I think that's a versioning problem.

Yes, thats the solution. Shouldn't it be ticked on default?
Thanks!

Yes, I believe this checkbox should be checked by default, let's see if sculpting guys can resolve the issue.

Will confirm again, since bod does not do that automatically

Ok I looked at this bug again and I don't understand what the issue is.

The vector displacement option should not be enabled by default as it changes how the texture is used for displacement. Most Draw brushes will not use this option.

If a brush is appended into a previous version of Blender that does not support this option then it's to be expected that VDM brushes break.

Can someone explain what needs to be fixed?
