Fighting sequences ( martials arts, Matrix style for example ) Normal behaviour ( take a glass and drink, take a book and open it, turn pages, open a door, sit on a chair, "inconscious" movement that we have when we have a conversation, etc. ): because they're normal and common actions, people have a particular knowledge of them, i.e.: a non-fluid movement/timing is easily noticed. A question: what is the application/system that you use to make the BVH - MoCaps? I'm trying VisualMarker but it requires a quite amount of job to follow manually the marker on the character's body ( and I still have to see the result i.e. the quality of BVH generated ) Best regards Fulvio
