GP refine strokes
Blender addon - Bunch of functions for post-drawing strokes refine
Where ?
Panel in sidebar : 3D view > sidebar 'N' > Gpencil > Strokes refine (need to be in a GP mode to appear)
Description
Various tools to affect strokes. Use F9 key to use the redo options when available.
The important things is that almost all the tools act according to the filter you define on top:
This is based on three level : Layer > Frame > Stroke. Be carefull with the targets.
If you tick Target last in paint mode, the target scope is overrided during draw mode and only last stroke is affected.
Selectors
Select backward/forward
Select strokes from the start or end of the stack in active frame
Select by length
Select stroke in active frame that are shorter than given length.
Hint: you can discard single points (considered 0 length strokes) in the redo panel
Select by angle
F9 to access angle tolerance tweaking via redo panel
Select hatching
Select lines with specific angle. Reference angle can be set with a selected stroke
Select attribute threshold
Select strokes or points if attribute (pressure, opacity) is below or above a given threshold
All the tweaking and options are available in the F9 redo panel
Stroke refine
Strokes Delete
Delete strokes from the start or end of the stack in active frame
Trim start/end (only work on last stroke)
each call erase starting/ending point. usefull to adjust when stroke has gone too far
Auto join (only on last stroke, /!\ experimental, need refining)
Merge the start of last stroke with nearest stroke tail found
head cutter tolerance : number (as points) from stroke boundary that are evaluated for the lines merge
Detection radius : Proximity tolerance to detect surrounding strokes boundarys, relative to screen space, increase if no result
straighten
Two buttons
One keep only first and last point so in-between point information like thickness are lost
The other straighten the point and you can affect influence.
shift+click to reset infuence to 100%
ctrl+click for homogen pressure
to Circle Tranform into average circle shift+click to reset infuence to 100% ctrl+click for homogen pressure
polygonize
Like the straighten above but by splitting on angles between point, user can manage angle tolerance.
Thickness and opacity
Modify the points attributes pressure or strength for targeted strokes (uses filter)
Can either set it or add/substract by some amount
Thin stroke tips
refine stroke by progressively fade pressure from middle to tip.
/!\ Works but kind of broken as for now, percentage is not accurate, can raise errors.
Infos
Print points infos: Display list of points pressure in console (according to filter)
Further notes
Filter management can be tricky sometimes (Need a rework to simplify common operation)
Examples:
Layer: Active, Frame: Active, stroke: Selected -> You can select strokes that are on different layer, but here your restricted to 'active layer'.
Layer: All, Frame: Active, stroke: Last -> Here last stroke is not necessarily the one on the active layer (since All layer are targeted)
keymaps
Alt + X
Bind Strokes Delete (see upper) to this shortcut
Allow to delete quickly the last bunch of strokes in active layer > frame
an infinite Ctrl+Z ;)
Todo:
- auto-join pressure : make a fade in pressure from chosen old points to new points
- auto-join subdiv : add an intermediate point to avoid a "break" in the line when the auto join
- feature action preference : make an addon preferences to change default options.
