Hi, I'm trying to animate using D3DXLoadMeshHierarchyFromX() and the animation controller. I have a problem but I don't realy know how to put it. I've already studied the MultiAnimation sample of the SDK but I don't quite get it. I've understanted the frame matrix update, the rendering loop and all. No prob here. What I don't understand, is how to use the same mesh to animate multiple objects that share that mesh. I'm assigning diferent animation controllers to the objects by using ID3DXAnimationController::CloneAnimationController(). What does this method do? Does it create a totaly new animation controller that is somehow connected to the mesh? Do I have to save the state of the animation for each object (time, animation track that is being played etc) and set it before the render?
