Short description of error
Significant slowdown in sculpting when using "alpha brushes" with images to sculpt detail on high poly mesh
Exact steps for others to reproduce the error
0. Download blend file and provided alpha image. Place both in the same folder
- Open provided blend file
- Switch to modifiers tab
- Add "subdivision surface" modifier
- Switch to simple and set "levels viewport" to 5
- Apply modifier
- Add "Multiresolution" modifier.
- Click subdivide until Sculpt/Render reaches 5
- This creates object with 6+ mln faces to sculpt
- Start sculpting with provided brush.
In 3.1.2 as long as brush is covering small area, it's very responsive. Once it gets bigger during dragging, there is a slowdown, but each next stroke goes back to being responsive as long as brush area is small. In 3.2 performance is very slow from the beginning.
First version I see this in is 3.2.0 and it continues to current release 3.2.2
