Character Transfer capture weights between characters

In Houdini, you can transfer attributes between objects based on their 3D proximity. One application of this feature is to transfer capture attributes to a new version of a character model with a different topology.

  1. Go to the SOP level containing the geometry between which you want to transfer attributes.

  2. Set the display flag on the geometry you want to transfer to. Select the node before the deform operator, if any.

  3. Set the footprint flag on the geometry to want to transfer from so it is also visible.

  4. If necessary, transform the models so they overlap each other in 3D as closely as possible. The attribute transfer operator works based on the proximity of the “from” and “to” geometry.

  5. In the viewer, use the tab menu to choose the AttribTransfer operator.

  6. In the network editor, select the model you want to transfer from, then click to finish the selection. The model will highlight in yellow.

  7. In the network editor, select the model you want to transfer to, then click to finish the selection. The old model will highlight in cyan.

  8. Select the new attribute transfer node in the network editor. In the parameter editor, on the Attributes tab, turn on the Detail checkbox.

  9. Turn off the footprint flag of the “from” geometry. The “to” geometry should have the transferred attributes.
