Description

In sidebar (N) > Gpencil > Toolbox

Addon preferences

important point of addon preferences:

Set path to the palette folder (there is a json palette IO but you an also put a blend and use a blend importer)

Note about palette : For now the importer is not working with linked palette as it's not easy for animator (there are properties of the material you cannot access and the link grey-out fade the real color in UIlist preview)

Environnement Variables

Mainly for devellopers to set project environnement

Since 1.5.2, following environnement variable can set the project properties in toolbox preferences at register launch:

RENDER_WIDTH : resolution x
RENDER_HEIGHT : resolution y
FPS : project frame rate
PALETTES : path to the blends (or json) containing materials palettes
BRUSHES : path to the blend containing brushes to load
PREFIXES : list of prefix (comma separated uppercase letters (2), an optional tooltip can be set after :, ex: 'LN:Line, CO:color, SH:Shadow') SUFFIXES : list of suffixes (comma separated uppercase letters of 2 character, ex: 'OL,UL')
SEPARATOR : Separator character to determine prefixes, default is '_' (should not be a special regex character)

Expose native functionnality

The panel expose some attributes that are too "far" in the UI:

• Zoom 1:1 - Camera view take 100% zoom according to current scene resolution (ops view3d.zoom_camera_1_to_1)
• Zoom fit - Adjust view so camera frame takes full viewport spac (ops view3d.view_center_camera)

• In Front - the In Front property of the object to get an X-ray view
• passepartout camera - enable/disable + set opacity
• button and sliders to enable / disable / set opacity of single background camera images

Edit line opacity - Animators usually like to hide completely edit lines to have a better view of the drawing in edit/sculpt mode, lowering opacity also allows a better reading on what's selected.
This options is stored per layer per object but this apply on everything at once.

Passive action

An "on save" Handler that trigger relative remap of all path can be enabled in addon prefs (disabled by default).
