Reduce Memory Usage
-
Remove ss->fmap need for normals -
Don't use active verts list but nodes-
Grab brush still needs to be converted
-
-
Separate undo stack for sculpt mode -
Only create DM origindex layer when needed. -
Only create sculpt face normals when needed. -
Store anchored original normals per node -
Store multires displacements outside .blend in a texture file -
Use more compact multires/subsurf DM - Remove ss->fmap need for smooth brush
Drawing
-
Show multires base resolution when navigating view -
Sometimes wrong partial redraw rect is generated, messing up window draw -
Sometimes normals are not updated in some places (on node boundaries?) -
Fall back to vertex arrays if VBO allocation fails. -
Make sculpt VBOs work with object mode VBOs, currently mesh disappears. - Support multiple partial redraws (for symmetry)
- PBVH drawing working for more draw modes
- Respect per face smooth/flat shading flags in sculpt mode.
- Some graphics card still have issues with partial redraw.
Multires
-
Change storage format so we have n grids for a polygon with n verts -
Store multires displacements outside .blend -
Add separate render level -
Add separate sculpt level -
Simple subdiv does not work well currently. -
Make smooth brush work again for multires. - Multires could do partial updates based on what changed when changing levels
- Make layer brush work again for multires.
- Grab brush can tear gaps in mesh sometimes (how to reproduce?).
- Restore old multires conversion code.
- Make interpolation work again in edit mode.
- Brush sometimes punches through to the other side with multires (need intersection epsilon?).
Performance
-
Multithreading for sculpting -
Multithreading for multires/subsurf code. -
Move PBVH to DM -
Reduce PBVH build time -
Take advantage of subsurf/multires structure for PBVH build - Low level optimizations for functions like brush drawing or normal updates (e.g. SSE)
- When sculpting can't keep up with the user, it would be good if Blender did not lock up but rather kept redrawing the brush and show intermediate results. A simple time limit to force an extra redraw + delay stroke updates could solve most cases.
Tools
-
Partial Refresh and Show Brush seem to not do anything -
Clicking outside of the mesh seems to lead to getting stuck in sculpting somehow. -
Make default falloff curve smooth instead of sharp (also nicer for paint). -
Shortcut keys for switching multires level - Falloff curve is not smooth enough. Could use bspline rather than cardinal interpolation (but only internally so user doesn't see it doesn't exactly go through points).
- Support maximum brush strength clamping, instead of always adding on top like airbrush?
- Hiding could use editmode flags? (especially for multires)
- Brush datablock management:
- One brush datablock for each type with own strength size
- Nicer list widget for browsing brushes, with previews?
- Shortcut keys for brushes
External File Storage
-
Integrate better with object remove/duplicate/.. .<s/> - <s>Make it work with library linking.
- Free memory after exiting lowering levels (e.g. exiting sculpt).
- Support loading only lower levels.
Other
-
Make sculpting shape keys work.
