The feature still has bugs: overlapping handles can be hard to select, only one Shape Key is visible at a time in Edit Mode, values become uneditable once armature and drivers are added, and shapes can deform or leave empty areas if moved too far (demonstrated with a Peppa Pig ear rig). Full integration is still in active development, with a linked pull request for tracking progress and downloading the test rig. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What problems occur when using Shape Keys with armature and drivers in Blender's Grease Pencil? Once armature and drivers are added to a Grease Pencil rig, Shape Key values become uneditable and their Bézier curves disappear from view. To adjust the Shape Keys again, the armature must be temporarily disabled, which limits fine-tuning during the rigging stage after bones are activated. _Riggers hitting Grease Pencil quirks can follow related Blender workflow breakdowns on daily.dev._ ### Why do Grease Pencil shapes deform when moved far with Shape Keys? Fill areas can fail to follow the bone's trajectory when a shape part is moved too far, causing the fill to fall out of the shape and leave empty gaps. This was observed on a Peppa Pig ear rig, where the ear's fill separated from the bone-driven motion path during testing. _Animators debugging shape key deformation issues can track Blender rigging tips on daily.dev._ ## Similar posts on daily.dev - [Check Out This 3D Animation Hand-Drawn Using Blender's Grease Pencil](https://daily.dev/posts/check-out-this-3d-animation-hand-drawn-using-blender-s-grease-pencil-tbgnbxkm7) · 80 LEVEL · 0 upvotes · 0 comments - [Make Weight Painting Easier With This Blender Tool](https://daily.dev/posts/make-weight-painting-easier-with-this-blender-tool-2thx9ronw) · 80 LEVEL · 0 upvotes · 0 comments - [Custom 2D-to-3D Workflow with Blender's Geometry Nodes & Grease Pencil](https://daily.dev/posts/custom-2d-to-3d-workflow-with-blender-s-geometry-nodes-grease-pencil-qup0mj33e) · 80 LEVEL · 0 upvotes · 0 comments --- Tags: [#3d](https://daily.dev/tags/3d), [#blender](https://daily.dev/tags/blender) [View this post on daily.dev](https://daily.dev/posts/shape-keys-for-blender-s-grease-pencil-tested-on-a-character-rig-gn8tcfhr0) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Shape Keys for Blender's Grease Pencil Tested on a Character Rig","url":"https://daily.dev/posts/shape-keys-for-blender-s-grease-pencil-tested-on-a-character-rig-gn8tcfhr0","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/shape-keys-for-blender-s-grease-pencil-tested-on-a-character-rig-gn8tcfhr0"},"datePublished":"2026-09-30T13:22:54.667Z","dateModified":"2026-09-30T13:23:15.177Z","description":"Artist Mumu Mundo tests the new Shape Keys feature for Blender's Grease Pencil tool on a character rig, showing how it lets animators define multiple states...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/c236da4a670e193cdc53695b1762371c?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/c236da4a670e193cdc53695b1762371c?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"80 LEVEL","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"80 LEVEL","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/78eebcd76c154e6bbfd565fed7dc4093","url":"https://daily.dev/sources/80lv"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/shape-keys-for-blender-s-grease-pencil-tested-on-a-character-rig-gn8tcfhr0","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"3d,blender","timeRequired":"PT3M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"80 LEVEL","item":"https://daily.dev/sources/80lv"},{"@type":"ListItem","position":3,"name":"Shape Keys for Blender's Grease Pencil Tested on a Character Rig"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/shape-keys-for-blender-s-grease-pencil-tested-on-a-character-rig-gn8tcfhr0#faq","mainEntity":[{"@type":"Question","name":"What problems occur when using Shape Keys with armature and drivers in Blender's Grease Pencil?","acceptedAnswer":{"@type":"Answer","text":"Once armature and drivers are added to a Grease Pencil rig, Shape Key values become uneditable and their Bézier curves disappear from view.
