Why we like it

Earns its place for tackling something Blender doesn't handle natively: moving vertex group weights from a mesh onto Grease Pencil strokes so drawings ride along with an existing rig.

What is Gp Transfer Weights?

GP Transfer Weights addresses a gap in Blender: the software lacks a simple way to transfer weights from a mesh to Grease Pencil strokes. This add-on transfers vertex group weights from a mesh to a Grease Pencil object. You paint over a rigged mesh in its rest position, then with one click the drawing follows the mesh animation.

An "Each Frame" option evaluates the source mesh weights at every keyframe and skins the Grease Pencil strokes accordingly. This lets you draw on top of an animated mesh and have the strokes skinned automatically later. It also works with separate drawings placed on different keyframes.

Built for Blender 4.2 to 4.5 as a compatible Blender extension add-on, it uses the Eevee render engine and is released under the GPL license by Malisan Luca. Documentation is included, and a demo video is available.

Who is Gp Transfer Weights best for?

How much does Gp Transfer Weights cost?

Gp Transfer Weights is completely free to download and use.

Frequently asked questions

Which Blender versions does GP Transfer Weights support?

GP Transfer Weights is built for Blender 4.2 through 4.5 and is listed as a compatible Blender extension. It installs as an add-on and uses the Eevee render engine. Within that version range you can transfer vertex group weights from a mesh to a Grease Pencil object and animate the strokes in sync with the mesh. If you're running a Blender release outside that range, check the developer's page for the latest compatibility details before installing so you know what to expect.

How does the Each Frame option in GP Transfer Weights work?

GP Transfer Weights includes an Each Frame option that evaluates the source mesh weights at every keyframe and skins the Grease Pencil strokes accordingly. This lets you draw on top of an animated mesh and have the strokes skinned automatically later. It also handles separate drawings placed on different keyframes. In the standard workflow you paint over a rigged mesh in its rest position and the drawing follows the animation with a single click.

Can GP Transfer Weights animate Grease Pencil drawings with an existing rig?

GP Transfer Weights transfers vertex group weights from a rigged mesh to a Grease Pencil object, so the drawing can follow the mesh animation. You paint over the mesh in its rest position, then with one click the strokes pick up the mesh's weights and move with it. For animated meshes, the Each Frame option extends this by evaluating weights at every keyframe and skinning the strokes accordingly, and it also supports separate drawings on different keyframes.

Is GP Transfer Weights free?

GP Transfer Weights is listed as free in this catalog and is released under the GPL license. Licensing terms can change over time, so check the developer's page for the current details before downloading. The add-on is distributed as a Blender extension add-on and comes with documentation, and a demo video is also available. For the specifics of how weights transfer from a mesh to Grease Pencil strokes, the included documentation is the place to look.
