Howdy,

Well, depending on the capabilities of your game engine, could you skin all the weapons to that weapon joint and toggle their visibility as needed?

Howdy,

You could try creating a “Weapon” joint or bone, add that as a child of the hand joint and then simply skin the weapon mesh to that weapon joint.

Howdy,

The joints in the 2 skeletons are not oriented the same. The BVH skeleton has the joints oriented with their Z axes pointing to the next joint down, while the skinned skeleton has all of the joints oriented with their Z axes pointing in the same direction as the World Z axis:

Howdy,

Oh, I forgot to mention that you also need to do the same thing for all the IK Pole Vectors.

Howdy,

You’d probably need to convert the character module rig to a fully editable rig and then manually set up the driver skeleton.

To set up the driver skeleton you’d first import a T-pose skeleton that matches your mocap import. Then create dummy NULL objects for each IK driver target and parent them into that T-pose skeleton. If your IK chains are targeting the rig controllers, you’ll need to create another set of NULL objects to serve as the actual IK Goals. Then constrain those IK Goals to the controllers and the IK driver targets. You can add a User Data slider and Xpresso setup to create the blend between the 2 targets in the constraints.

It will be a lot of work, but once you get it done, you can probably reuse that rig for other characters.

Howdy,

One of the problems with applying motion capture to a rigged character is that the imported motion capture skeleton may not have the same joint twists as the skeleton to which the mesh is bound.

The easiest ways to handle it is to create 2 joint skeletons for the character. One rigged normally with IK and constraints, etc., to which the mesh will be bound, and the second skeleton to be used as a driver skeleton for the first one. What I mean by “driver” skeleton is that within that second skeleton, parented to specific joints will be target nulls to which the IK goals can be targeted, so that the second skeleton can drive the IK of the first skeleton.

You would then retarget the motion of the imported mocap skeleton to the driver skeleton, which will in turn drive the IK skeleton.

Here is an example of a driver skeleton driving an IK skeleton with a blend between the 2:

… and an example with a bound mesh:

It takes a little work to get the initial rig set up with the IK and driver skeletons, but once that is done, that can be your standard rig from there on out.

February 22, 2012 at 1:39 pm in reply to: Animation Slowing Down

Howdy,

There is an option called “All Frames” that is usually enabled by default. If you disable that option, it will skip frames in an effort to keep the playback as close to realtime as possible:

There is a point, though, when your scene gets to heavy, that with that option disabled it will be too choppy. That’s when you have to start rendering editor previews to view the animation in realtime.

Howdy,

You should at least post an image of your weighting so folks here can get an idea of what’s going on.

Howdy,

There was a small bug fixed in the CD FBX Import/Export plugin that caused an error in the skinning when importing IK and Aim constraints on rigged/skinned characters.

You can download the updated version here:

Also, I’ve uploaded the Basketball Character rig that was used in the demonstration video to my Free Rigs page:

Howdy,

You might be running the 32bit version of Cinema 4D. There should be 2 executables:
Cinema 4D.exe (32bit)
Cinema 4D 64 Bit.exe (64bit)
