Clay brushes "Front Faces Only" still affecting backfaces
Confirmed, NormalPublic


System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GTX 1650 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 441.20

Blender Version
Broken: version: 2.90.0 Beta, branch: master, commit date: 2020-08-25 16:00, hash: rB21cb6f09ffa8
Worked: 2.83 LTS (Not working perfectly, but better)

Short description of error
Clay sculpt brushes (Clay Strips, Clay) - Only when adding clay (not carving in), affects geometry of the other side(extruded hole for example) (with high enough brush radius). "Front faces only" option does not help.

2.83 Seem to be working better(not perfect), issue seems to be worse in 2.9+
(Would be great with an option to tweak Depth value on brushes manually)

Bigger brush radius seems to be the issue, however this is a problem that only affects Clay brushes.

Exact steps for others to reproduce the error

  1. Open file
  2. Sculpt

One side is pre-damaged for demonstration.
