Deformer Graph vertex attribute

Development Character & Animation

Hi,
trying to achieve the following:

  • define a new vertex attribute (AddWeightMapLayer in Skeletal Mesh / Editing Tools / Skin)
  • paint the parts of the skeletal mesh that needs to be affected (Skin / Paint Maps, and select the name of the new attribute)
  • in the deformer graph I’m using the node Skinned Mesh Vertex Attribute, where the input is the name of the new vertex attribute
    The expectation is that I will receive the new attribute value per vertex, instead only zeros.
    Any idea what I’m doing wrong? Is there are any other way to specify parts of the mesh that needs to be affected by the deformer graph?

Regards

Thanks for the question! Sorry for the delayed response.

Currently, new vertex attributes are not enabled by default. Once you create the attribute, you will need to go to SkeletalMeshEditor → AssetDetails → LOD# → LODInfo → Vertex Attributes → Enable or Rendering to actually enable it for specific LODs

we understand that this is not intuitive and will seek to improve it! Hope this helps!
