System Information
Operating system: Linux-5.3.0-46-generic-x86_64-with-debian-buster-sid 64 Bits
Graphics card: Mesa DRI Intel(R) UHD Graphics 620 (Kabylake GT2) Intel Open Source Technology Center 4.5 (Core Profile) Mesa 19.2.8

Blender Version
Broken: version: 2.90 (sub 2), branch: master, commit date: 2020-05-20 20:56, hash: 8a0840b0ee
Worked: (newest version of Blender that worked as expected)

Short description of error
[Please fill out a short description of the error here]

Sculpting: Shape Keys: Sculpting should show the mesh using a shape key value of 1.
This should work similarly to when enting edit mode while using shape keys;
the mesh should shown using a value of 1 and the value slider in the shape key panel should be greyed out.

This was found with D7826

Exact steps for others to reproduce the error

  • . Create base shape key and a second key
  • . modify the mesh of the second key
  • . set value to 0
  • . Enter edit mode and then sculpt mode comparing the differences.

On the one hand this looks like a bug, since it is not possible to sculpt a shapekey with a value of 0.0.
On the other hand, it may be useful to sculpt one or more shapekeys with different values at the same time.

Seems to be a design that still needs to be discussed.

Looks a bit like undefined behavior, yes.

It is useful to sculpt with multiple shape keys enabled: this is vital for making relative shape-keys.

I'm not so sure about the usefulness of the active shape key not being shown at full strength, though. I can't count how many times I've sculpted on a key with no influence!
