I had seen in some documentation or example that there is a patch articulation feature that “fuses” the gaps in animation puppets - Which product is this available in Animate or Animate Pro?
I am not sure if you are looking for an actual feature or a way to work there. Creating patch is a technique used to basically erase the joint lines in cut-out character to have the character look as if it we made of one big piece of material instead of seeing the joints.
The creation of patch is actually covered in the user guide that come with both Animate and Animate Pro.
If you are looking for an automatic feature to do those patch I suppose you are looking for the glue effect. This is only available in the Animate Pro version.
