The Get DNA Blendshape node

When to use it

One named blendshape target out of a DNA, as a mesh, optionally filtered to the expression that uses it. Good for inspecting or re-sculpting a single shape. For the combined result an animator would actually see, Get DNA Expression.

Use the expression filter. A DNA carries hundreds of blendshapes, and without it the dropdown is a wall of names you have to read end to end.

Dual quaternion skinning changes the posed result, so keep it consistent with whatever you will use when writing the shape back. Otherwise the delta you author gets measured against a different baseline.

How to use it

  1. 1

    Wire a DNA in, and the mesh from DNA To Mesh into Mesh

  2. 2

    Pick a blendshape

    Filter by expression first if the list is unwieldy.

  3. 3

    The Mesh output is the same mesh with that shape on it

    The mesh you feed in has to be the same mesh at the same LOD, with the same vertex count. Anything else and the node stops with a count mismatch.

Pins

Pin Type Description
DNA DNA The DNA to read the blendshape out of.
Mesh Mesh The mesh to put the shape on. Same vertex count and order as the DNA's own mesh, so use DNA To Mesh at the same LOD.
Pin Type Description
Mesh Mesh The same mesh with the shape applied on top of whatever pose it was already in.

Settings

Setting Type Description
Blendshape Name Text Which blendshape target to apply. Nothing shows up in the dropdown until a DNA is wired into the input pin.
Filter By Expression Name Text Cuts the blendshape list down to the ones a single expression drives. Leave it empty to see every target in the file.
Use Dual Quaternion Skinning True/False Skins the blendshape offsets with dual quaternions rather than linear blending, which holds volume where a joint twists. Set it to match how the character itself is skinned.
